inference

gmatmachoman wrote:@ Pheonix, I could see this as a " inference question" rather a conclusion one.

IMO C infers data from the argument stated.

Let us assume total number of high school seniors = 100

Recent study results (one-third of high school seniors say that they have “significant financial responsibilities): 33 high school seniors


a second study:
80% of high school seniors have never taken a personal finance class even though the same percentage of seniors has opened bank accounts and one-third of these account holders has bounced a check.

---80 % of 100= 80 students have never taken PF course.

and the same 80 students have opened bank accounts.

one-third of these account holders has bounced a check.

(1/3) of 80 =27.

So from the above data, 33 > 27 ; the number of high school seniors with significant financial responsibilities is greater than the number of seniors who have bounced a check.


But I don't agree this as a conclusion based CR.

IMO C

one-third of high school seniors say

80% of high school seniors

"significant financial responsibilities." ........include, but are not limited to, contributing to food, shelter, or clothing for themselves or their families

If you assume 100 seniors were questioned, can you be sure if the same 100 were questioned in the second survey?
Case might be, there were only 50 seniors in the second one and 80 % said blah blah blah.....

got my point?

pkw209 wrote:This one is tough but I agree with harshavardhanc's logic about sample size. The passage never says that both surveys are comprised of the same number of people. You could have 100 in the first survey and 1000 in the second, which would destroy c.

However, the only way C holds is if we assume that both surveys have the same number of people. Kinda bogus but what can you do?

pkw209 wrote:"At the same time" to me doesn't imply that they have the same sample size. I think the phrase serves the purpose of switcing gears and emphasizing a different set of results.

oh well.

These responsibilities include, but are not limited to, contributing to food, shelter, or clothing for themselves or their families. At the same time, a second study demonstrates that a crisis in money management exists for high school students. According to this study, 80% of high school seniors have never taken a personal finance class even though the same percentage of seniors has opened bank accounts and one-third of these account holders has bounced a check.

Which of the following conclusions can be properly drawn from the statements above?
a)High schools would be wise to incorporate personal finance classes into their core curricula.
b)At least one-third of high school seniors work part-time jobs after school.
C)The number of high school seniors with significant financial responsibilities is greater than the number of seniors who have bounced a check.
d)Any high school seniors who contribute to food, shelter, or clothing for themselves or their families have significant financial responsibilities.
e)The majority of high school students have no financial responsibilities to their families.
