A survey recently revealed a high correlation between a [#permalink]
 11 Jul 2011, 12:52
Question Stats:
23% (02:00) correct
76% (01:21) wrong based on 26 sessions
A survey recently revealed a high correlation between a household's level of education and its library. Specifically, the more years of college and graduate school education received by the household's members, the more books in the household's library. The survey also indicated that the higher the education level of the household, the greater the percentage of books that are not works of fiction in its library. Which of the following can be properly inferred from the survey results cited above? A) People with a higher level of education prefer reading nonfiction to works of fiction. B) Households with low education levels generally own more works of fiction than do households with high education levels. C) Households with lower levels of education generally own more works of fiction than nonfiction. 4) The higher the education level of a household, the fewer works of fiction owned by the household. 5) Households with high education levels generally own more nonfiction books than do households with low education levels. Please explain your answers.

the most important thing to notice is the term percentage .The survey also indicated that the higher the education level of the household, the greater the percentage of books that are not works of fiction in its library. the argument essentially states that higher the education level OF A household the higher percentage of non-fiction works are generally present in it's library.
A) Wrong . no such data is given. the author only says percentage of non-fiction books increases in families with higher level of education. ABSOLUTE VALUE OR PREFERENCE IS NOT GIVEN. ex- families with members who have done BA can have 20 % non-fiction in their library and families with members who did MA can have 30% non-fiction. The percentage of non-fiction books increased in Ma families(higher educated) but overall preference is still for fiction. (70%)
b)if it was more percentage of fiction, then it would have been right.
c)again we don't know absolute data.
d) again if it was fewer percentage it would have been right.
e) bang on ! the survery also stated that more years of education the more books a family owned. combined that with another finding that more educated a family more percentage of non-fiction book it reads, we come to this conclusion.

+1 for E.
From the argument
1) Total Books in High education level households > Total books in low edu. level
2) % of non fiction books is directly proportional to education level.
Now % of non fiction books = Number of non fiction books * 100 /Total no of books.
Hence if % of non fiction books is higher in High education level households, it follows from above equation that Number of non fiction books will also be higher. (since denominator is larger for high education households).

In My opinion, it should be 'D' 4) The higher the education level of a household, the fewer works of fiction owned by the household. Reason : "the higher the education level of the household => the greater the percentage of Non-fiction books in its library" Because we are just talking about One household & two kind of books, percentage inherently tells the relationship between the number of two kind of books. And 'D' exactly does that. Besides why I don't think 'E' as correct answer, because nowhere in the argument , there is any direct mention of 'households with low education levels'

For me should be D if we talk of % we have for instance 10% of fiction and the rest no fiction, and this is what the conclusion say: it states not that the whole books are fiction or viceversa, and nothing tells about low education.

E it is ,
D suggests that if the education level of the households increases , the number of non fiction books with the household will decrease; however this is not the case.
What if the education level of the households increases and households buy more fiction books but maintains the same number of nonfiction books ?
