In a study conducted in Pennsylvania, servers in diverse restaurants wrote "Thank y'all" on randomly selected bills before presenting the bills to their customers. Tips on these bills were an average of iii percentage points higher than tips on bills without the message. Therefore, if servers in Pennsylvania regularly wrote "Thank yous" on eatery bills, their average income from tips would be significantly higher than it otherwise would accept been.
Which of the following is an assumption on which the argument relies?
(A) The "Thank you" messages would have the same impact on regular patrons of a restaurant as they would on occasional patrons of the same restaurant
(B) Regularly seeing "Thank yous" written on their bills would not atomic number 82 restaurant patrons to revert to their earlier tipping habits
(C) The written "Give thanks you" reminds restaurant patrons that tips constitute a significant role of the income of many food servers
(D) The charge per unit at which people tip food servers in Pennsylvania does non vary with how expensive a restaurant is
(Due east) Virtually all patrons of the Pennsylvania restaurants in the study who were given a bill with "Thank you" written on it left a larger tip than they otherwise would have.

The argument states that waiters who write "thank yous" on the pecker on average get 3% higher tips on checks than those who don't. Therefore, the waiters believes that if they will get a more than tips if they write "give thanks you" on each receipt. The questions asks for the supposition that the waiter's belief relies upon.
A. The "Thank you" messages would have the same affect on regular patrons of a eating place as they would on occasional patrons of the same restaurant. The question does not distinguish betwixt occassional and regular patrons. It only states that the patrons who see "Cheers" pay tip three% higher than those who don't take "Cheers" on their checks.
B. Regularly seeing "Give thanks you lot" written on their bills would non lead eatery patrons to revert to their before tipping habits.If this is true then it would non undermine the decision that people who see "give thanks yous" volition tip more.
C. The written "Thank you" reminds eatery patrons that tips constitute a significant function of the income of many food servers. This statement is non necessary considering it touches upon the reason why people might pay more. ie. Patrons could be paying more bc the "Thank you" makes them think that their waiter is friendlier. This does not undermine the conclusion.
D. The charge per unit at which people tip nutrient servers in Pennsylvania Does non vary with how expensive a restaurant is. Out of telescopic.
Due east. Virtually all patrons of the Pennsylvania Restaurants in the study who were given a pecker with "Thanks" written on it left a larger tip than they otherwise would accept.This is not an supposition made to describe the determination. This is the issue of the study.

is it E>>>coz the argument is assuming that the note 'Thank you' is responsible for the college tips, whereas it is not taking into account the usual tip giving habits of customers....it culd exist such a case where all the particular bill payers, generally go out a higher tip than the general public...

Re: In a report conducted in Pennsylvania, servers in various restaurants [#permalink] 07 Aug 2009, 08:41
I like your explanations on B every bit that was how I thought it should be. And the OA is B too.
But, is there annihilation incorrect with A? Can't A function as an assumption also?
You see, if the impact was the same for both kinds of patrons, wouldn't A become an assumption that supports the argument?
I heard of the technique "If Yes/No" assay. Shall we utilize it to go through choices A and B? From what ppl say, if an answer selection could support/weaken an argument whenever it switches from "If Yeah" to "If No" or vice versa, and so that is probably a correct reply. Choices that could not back up or weaken whenever you use "If Yes" or "If No" would non be a correct reply. [Delight, someone right me if im wrong here]
For A
If Yeah, A supports/strengthens the statement.
If No (ie. bear on is different for both sets of patrons; some might tip a bit more than and some a fleck less, just ultimately all of them on average would tip more than than previously), A cannot weaken the statement either. In fact, if you expect closely, B actually still supports the statement.
Since both "If Yeah/No" can only support the statement (Fifty-fifty when you swith to "If No", you still cannot weaken it), and so this is probably not the answer.
For B
If Yes, B supports the statement. The reasonings are as provided by the previous posts
If No, B weakens the argument instantly. Say, if the patrons would revert dorsum to tipping less, then the argument weakens.
Since both "If Yep/No" can support and weaken the argument, then this is probably the correct answer.
Hmm.... please permit me know if you lot hold with my line of reasoning as it tin can be a scrap hard to put it in words.
Thank you.

Re: In a study conducted in Pennsylvania, servers in diverse restaurants [#permalink] 29 Dec 2009, 12:59
I'k pretty sure it'southward E. Google it for me. I'm at work and can't access sites with the OA on them. This question was posted earlier on GMAT Guild earlier, though. Here'south why I think information technology's East.
Quote:
In a study conducted in Pennsylvania,Servers in various restaurants wrote "Thank you" on randomly selected bills before presenting the bills to their customers. Tips on these bills were an average of three percentage points higher than tips on bills without the message. Therefore, if servers in Pennsylvania Regularly wrote "Give thanks you" on restaurant bills, their average income from tips would be significantly college than information technology otherwise would have been.
This explicitly assumes a cause and effect relationship with the cheers causing the 3% tips increase. At that place could have been several reasons why these waiters got higher tips. They may have been more customer focused and therefore worked harder- and the Thanks might have just been the icing on the cake rather than the cake itself. The point is that there is cipher in the stem that says we tin control for the differences in service among the servers. Eastward addresses this dead on IMO.
E. Virtually all patrons of the Pennsylvania Restaurants in the study who were given a bill with "Thank you" written on information technology left a larger tip than they otherwise would take.
East displays this cause and affect and is more just the result of the report because the evidence of the study doesn't necessitate that the Cheers's were the cause of the increased tips. Due east'southward the missing link. B IMO is a booby trap answer. It goes across the scope of the claim. Where in the merits is "regular tipping habits" divers or mentioned. Who has the habit? - those in the Thank you group or those who aren't? I'd argue that both probably have tipping habits. Is B arguing that the Give thanks yous's would desensitize patrons to the Thanks's? Nevertheless, That's a future statement. The actual claim is about what the servers "could take" received so information technology'due south in the past.
Any way these are simply my thoughts sometimes I'thousand wrong. But if B is the respond I can't see information technology's logic at all. I can see Due east'south.

Re: In a report conducted in Pennsylvania, servers in various restaurants [#permalink] 29 Dec 2009, 14:37
Hither's my reasoning for why it's not E. The conclusion is that if waiters write "thank you" on the checks, so they volition receive a higher tip. The decision is drawn from the fact that in a previous study those who wrote "thanks" received 3% higher tips than those who did not.
Co-ordinate to E. Nigh all patrons of the Pennsylvania Restaurants in the study who were given a pecker with "Cheers" written on it left a larger tip than they otherwise would have. This non an assumption that the determination depends on. Not all the patrons need to leave more tip than they otherwise would have in order for the conclusion to be drawn that writing "thank yous" volition increase the tip. The question states ON AVERAGE those who had "thanks" tipped iii% college. Perhaps merely half of the people left a higher tip. Mayhap only a quarter left a higher tip. Or peradventure only one person left a higher tip (a really really big tip). The number of patrons who left a higher tip does not affair in this argument. It'southward merely stated that ON Boilerplate tips were three% higher. If the "thank you" induced anyone at all to leave a higher tip then they would have, then the overall tip would exist college.
Vannbj, I understand your reasoning that it'south possible that the patrons who got "thank you" on their nib were incidentally the ones who also got better treatment from the waiters. Therefore the better service and not the "thank you" per say was the reason for the higher tip. However, statement E says that nigh all patrons of the Pennsylvania Restaurants in the written report who were given a neb with "Cheers" written on it left a larger tip than they otherwise would accept. Aye this argument does distinguish that the "thanks" was the cause of the higher tip, merely similar I mentioned earlier, it's non necessary for almost all of the patrons to tip more than in order for the conclusion to be drawn.

Re: In a study conducted in Pennsylvania, servers in diverse restaurants [#permalink] 11 Nov 2011, 09:44
Heres the explanation:
Choice A states that both regular patrons and occasional patrons of the restaurant will be impacted in a similar way on seeing the 'Thank You' note. Notwithstanding, the impact is non mentioned clearly and hence this is out of scope.
Option B states that seeing the 'Give thanks You' note regularly would not lead eating house patrons to revert to their before tipping habits. Thus, this selection eliminates the possibility that would weaken the statement. In other words, using the supposition negation technique, we tin see that if the patrons revert to their earlier tipping habits on seeing the note regularly, the average income of the servers would not be higher. This contradicts the original statement which concludes that higher tipping on seeing the 'Thank you' note will lead to a higher income for the servers. Then this is the correct respond option.
Choice C seems to exist a chip far fetched because in order for this pick to be right, we demand to assume that the patrons would tip college as they would think, on seeing the cheers note, that the tip is a significant function of the servers income.
Pick D seems to be out of telescopic as we are non concerned with how expensive or less expensive a restaurant is.
Option Due east seems to be irrelevant also considering it adds on to the given premise that tip was loftier when the bill was accompanied by a Thank Yous note.
Promise this helps.
Thank you!

Again, as in such questions, there are ordinarily 2 very strong possible answers. In this case, it is A or B. Somehow, I don't discover the OA respond very convincing.
We do i report and conclude that nosotros can continue the practice "regularly" and continue to reap the aforementioned benefits.
B is the just assumption that is required to make this conclusion.
A) not a necessary assumption. even if it had different effects and all regular patrons could have tipped much more to generate the extra iii% in tips or it could have been the other way around.
C) Whether the notes remind the patrons of something, insults them or applauds their generosity is exterior this give-and-take. Nosotros are only focused on the terminate upshot of more tips.
D) The tipping rate could be dissimilar for restaurants. We are comparing previous tipping charge per unit at the aforementioned eatery, not across various restaurants.
E) All (or for that affair significant) number of patrons don't have to leave a larger tip. Only few may be leaving big plenty tip to get the "average" 3% college tipping rate.
hope this helps.

The reply is definitely B.
B. Regularly seeing "Cheers" written on their bills would not lead eatery patrons to revert to their earlier tipping habits.
Let's negate B. Regularly seeing "Give thanks you" written on their bills will lead restaurant patrons to revert to their earlier tipping habits.
If they revert, the argument falls apart and the substantial increase in tips is non possible. So past negating B nosotros can hands deduce that it is the correct answer.

IMHO:
X: regularly write "Thank you" on nib
Y: avg income from tip is higher
Conclusion: Causation: Ten causes Y
Assumption: Ten does not cause (not Y) (not Y = "revert to their tipping addiction = tip less")

Premise: RANDOM TY NOTE -> INCREASED TIPS GAP: RESULT THAT WAS OBSERVED ON "RANDOM" ACTS WILL HAPPEN WHEN THIS IS Done "REGULARLY"
Conclusion: REGULARLY WRITING TY Notation -> INCREASED TIPS
Which of the following is an supposition on which the argument relies?
A. The "Thanks" messages would have the aforementioned impact on regular patrons of a restaurant as they would on occasional patrons of the same restaurant.
No need to assume on the behavior of regular vs occasional patrons... The issue is Random TY Writing vs. Regularly Writing TY Noes..
B. Regularly seeing "Thank you" written on their bills would not atomic number 82 eating place patrons to revert to their earlier tipping habits.
If Regularly doing so volition lead to reverting to earlier tipping THEN the conclusion is invalid. This is the assumption.
C. The written "Thank you" reminds eating house patrons that tips constitute a significant part of the income of many food servers.
What TY note reminds the customer was non mentioned in the stimulus
D. The rate at which people tip food servers in Pennsylvania Does not vary with how expensive a eating place is.
We are concerned with boilerplate tips collected. The variation is non our business concern.

Re: In a study conducted in Pennsylvania, servers in various restaurants [#permalink] Updated on: 21 Jul 2013, 22:02
In a study conducted amidst servers in restaurants in Canada, information technology was observed that the tips on bills with a "Thank you " note fastened were on an average three percentage points higher than those without the note. Thus, regularly writing Thanks on the bills volition increase the boilerplate income from tips significantly.
What is the assumption on which the argument depends.
A) the cheers would accept the same outcome on regular patrons of the eatery as on the occasional ones
B) regularly seeing thanks written on the bill will non make the customers alter their tipping habits.
C) The cheers reminds restaurant patrons that tips found a major role of the income to the servers
D)The rate at which the customers tip does not vary with how expensive the restaurant is
E) Nigh all patrons of the eating place who were given a pecker with a thank yous written on information technology left a larger tip than they would have.
The clear assumption in this question is that the patrons of the restaurant will continue their tipping habits,fifty-fifty afterwards regularly seeing a Thanks written on the neb.
Considering option A: If the regular patrons contribute towards a larger portion of the revenue earned by the eatery, the tips that they give will likewise plant a significant part of the total income received from tips. In this case, if regular patrons are not affected by the new thank you note, boilerplate revenues might not go upwardly significantly- the primal word here.
On the other manus, if regular patrons found a very small proportion of the customer base, so whether they tip higher or non does not matter at all as far as significant increase in revenues from tips are concerned.
Regular patrons total customers
20 1000 -very small effect
700 one thousand -significant result
So, does the argument equally it is stand up equally a strengthener?
Also, option A says that the thank y'all will have the aforementioned effect on both regular ones and not regular ones? What event is this, nosotros exercise not know. It could mean that both are afflicted in a way that they tip higher or both are affected in a style that the thank you has no effect. Or are we to assume that the result being talked about in this pick is that they volition tip higher?
Suppose we change this argument- " Regular patrons are as likely to tip higher than are occasional patrons"-
Now, nosotros don't know how likely the occasional patrons are to tip. If the likelihood is high- revenues volition become upwardly. If not, and then revenues will not go up.
What practice you lot think?
Could you propose possible strengtheners?

At present, we don't know how likely the occasional patrons are to tip. If the likelihood is high- revenues will go up. If not, then revenues will not go upward.
What practise you call back?
Could you suggest possible strengtheners?
The conclusion uses the give-and-take "significantly". Because we do not know the percentages, A as it is NOT a strengthener. Information technology could either increase the income significantly or non, it depends on how many regular/occasional consumers the restaurant has and how much tips they left.
We have to assume that the result will be college tips. Considering if the same effect were "no effects", then who left the tips?
A strengthener here IMO could exist something like:
"All consumers who were given the "thank yous" bill left a tip, and came dorsum to the restaurant presently afterwards"
This shows two things:
1)The effect of the bill are predictable and affect all consumers (so the case: "one consumer left a thou$ bill, the other none, and the average was 3%" is not a realistic scenario).
2)This procedure does non discourage consumers, because they returned to the eatery.
Hope this helps

In the context of the passage, "significant" ways around iii%. The argument tin't sensibly refer to a sample in which tips increased by 3% and say that in the future it will exist a x% increase.
Secondly, we don't know how much of the revenue of the eatery or tips of the servers are generated from regular patrons or from occassional patrons, so comparing them does not help united states of america any bit. We don't know about whatever of these and the choice statement makes a comparison betwixt these two.

Regular patrons full customers
20 k -very small issue

Then, does the statement as it is stand up equally a strengthener?

Now, we don't know how likely the occasional patrons are to tip. If the likelihood is loftier- revenues will go upwardly. If non, so revenues volition not get up.
What do you think?
Could y'all suggest possible strengtheners?
Any you lot do with option A, it is going to remain on OFS respond choice till it keeps comparing regular patrons with occasional ones. We don't know virtually whatever of these. What would nosotros gain by a comparison of these two? If we had known about tipping habits of one category of guys, then, past comparison, we might have gained something but as is, option A is completely not-nonsensical and out of scope.

B. Regularly seeing "Thank you" written on their bills would not atomic number 82 eatery patrons to revert to their earlier tipping habits.
C. The written "Thanks" reminds eating house patrons that tips constitute a significant part of the income of many food servers.
D. The rate at which people tip food servers in Pennsylvania Does not vary with how expensive a restaurant is.
Eastward. Almost all patrons of the Pennsylvania Restaurants in the study who were given a bill with "Thanks" written on it left a larger tip than they otherwise would have.
determination:write regularly Thank you on restaurant bills ===> income with tip will ascension significantly i.e three pct (as per the argument)
premise: written report conducted on various restaurant ==>bills with give thanks you earned 3 percent more tips.
A. The "Give thanks y'all" letters would have the same touch on on regular patrons of a eatery every bit they would on occasional patrons of the same restaurant.==.any is the effect of patrons whether they are regular or occasional patrons==>terminate result is that we have received 3 percent more than tip which is already proved in premise...==>and so this has no result.
B. Regularly seeing "Thanks" written on their bills would not lead restaurant patrons to revert to their earlier tipping habits.
now according to premise we gained three percent increment on tip having thank you lot bulletin in an experiment.
that was only in the experiment menstruation.what is different in that experiment period and the decision?
the only difference is that time duration==>THE experiment was/must be for some flow of time==>in conclusion we are putting THANK Yous message regularly....so thats the only difference if that gene doesnt affect and then or decision is perfect.hence this is right
C. The written "Thank y'all" reminds restaurant patrons that tips constitute a significant part of the income of many food servers.
nosotros are not concerned what it reminds or not==>if it reminds and then it was reminding besides during experiment also and viceversa.
so if you negate==>information technology doesnt remind===>this ways experiment was successfull in the absence of reminder...so this i doesnt affects conclusion.
D. The rate at which people tip food servers in Pennsylvania Does non vary with how expensive a restaurant is.
again same every bit A...we are non concerned how it affects in different types of restaurant ==>end result is we are getting 3 pct increase in tip.
hence out of scope.
East. Virtually all patrons of the Pennsylvania Restaurants in the report who were given a bill with "Cheers" written on information technology left a larger tip than they otherwise would have. ==>once again conclusion doesnt depends on this because whether the increment was because of ALL or because of SOME we are non concerned.
hope this helps

Re: In a report conducted in Pennsylvania, servers in diverse restaurants [#permalink] 29 Oct 2013, 22:52
I just looked through the explanations, just just wondering why the answer can't exist D.
I thought that if the answer to the statement D. is
i. Aye, Then when people perceive sure restaurants are more luxurious than others, they volition give more tips.
2. No, Then they gonna tip less
To make this argument to be true, don't we have to asssume that this is an assumption?
I thought this statement works equally a defender??? or I merely misunderstood?
Could anyone please explain this for me??
Thanks

Hi Phunneyz
Glad to assist 
First of all, this question is about defender supposition. Y'all're correct. But you lot misled the point considering you did not determine the conclusion correctly (I guessed). The decision is " Therefore, if servers in Pennsylvania Regularly wrote "Thank you" on restaurant bills, their average income from tips would be significantly higher than it otherwise would have been"
--OR--
The more "cheers", the more tip for servers. <== This is the point, it doesn't matter how expensive a restaurant is. The KEY is the relation betwixt the frequency of the "cheers" shown on a bill with the average tip.
Every bit you lot knowthe KEY of defender supposition is to ELIMINATE answers that can weaken the decision. That differs from supporter supposition that will close the gap between premise and conclusion. Just a small-scale remind of theories.
Now look back to D.
D. The charge per unit at which people tip food servers in Pennsylvania Does not vary with how expensive a restaurant is.
Practice yous think D weaken the conclusion? Nope, D simply talks about the rate of tip varying with how expensive a restaurant is, Just Non with how frequently the "thanks" is written on a bill. Practice not infer likewise far, y'all should stick to the information provided in the argument. In fact, the argument does not say almost the expensive of a restaurant.
Hope it helps.
