Question Stats:

0% (00:00) correct 0% (00:00) wrong based on 2 sessions
A medical journal used a questionnaire survey to determine whether a particular change in its format would increase its readership. Sixty-two percent of those who returned the questionnaire supported that change. On the basis of this outcome, the decision was made to introduce the new format.

Which one of the following, if it were determined to be true, would provide the best evidence that the journal's decision will have the desired effect?

(A) Of the readers who received questionnires, 90 percent returned them.
(B) Other journals have based format changes on survey results.
(C) The percentage of surveyed readers who like the format change was almost the same as the percentage of the entire potential readership who would like format change.
(D) It was determined that the new format would be less costly than the old format.
(E) Ninety percent of the readers who were dissatisfied with the old format and only 50 percent of the readers who like the old format returned their questionnaires.

Please explain with answer

A - Doesn't help.
B - Not relevant
C - Best choice. Says that the 62% of the readers will like the change. Since most READERS like the change, it will have the desired effect.
D - Outcome is not based on the cost but on the survey.
E - Doesn't say whether the 90% will like the new format!

C, as per gsr's reasoning!
In addition, C is also about potential readership, which can become actual readership if the format change is well received.

(A) Taking in account this, it is only certain that 55.8 percent of the readers want a change.
(B) Irrelevant
(C) Taking this into account, 62 percent of the readers want a change
(D) Irrelevant
(E) In this case, the survey carried out is not relevant.

So the best choice is C

B,D and E are not relevant
Between A and C, I go with A.

Choice A says the % of the percentage of readers who receive questionnaires, 90% of them particiapted. Assuming there are 100 readers, 90 receive the questionnaire and participated. Of these 90 people, about 55 of them votes for a change

Choice C is not very good. It says the % of surveyed readers who wants a format change is about the same % of entier potential readership who like a format change.
Assuming there are 100 readers again, but only 10% of the readers (10 readers) wants a format change. 90 readers are surveyed, 10% of these (9 readers) say they want a format change. Does this represent that more readers want a change? Not quite.

I'll take A.

C should be the answer. the passage doesnot say that 90% of the readers who received the questionire participated in the survey. rather it says 90% of the readers who received the questionire participated in the survey.

suppose, total readers = 1000
questionire sent to = 300 readers
participated = 270 readers
favor the change = 60% of 270 = 162 readers.

so out of 1000 readers only 162 favor the change. so it is not strong enough to conclude the change is favored by majority of the readers.

C says that the % of the readers who like the change in formate for the readers who were not surveyed is (60%) the same as the readers who were surveyed. it means in general, 60% of the journal's readers favor the change in format...... so C wins...

You're right. I made a wrong calculation.
