The proportion of women among students enrolled in higher [#permalink]
 16 Apr 2007, 00:00
Question Stats:
0% (00:00) correct
 0% (00:00) wrong based on 0 sessions
The proportion of women among students enrolled in
higher education programs has increased over the past
decades. This is partly shown by the fact that in
1959, only 11 percent of the women between twenty
and twenty-one were enrolled in college, while in
1981, 30 percent of the women between twenty and
twenty-one were enrolled in college.
To evaluate the argument above, it would be most
useful to compare 1959 and 1981 with regard to
which of the following characteristics?
(A) The percentage of women between twenty and
twenty-one who were not enrolled in college
(B) The percentage of women between twenty and
twenty-five who graduated from college
(C) The percentage of women who, after attending
college, entered highly paid professions
(D) The percentage of men between twenty and
twenty-one who were enrolled in college
(E) The percentage of men who graduated from high
school
OA: D I answered E!

A) The percentage of women between twenty and
twenty-one who were not enrolled in college - does not affect the conclusion that a higher proportion of women 20-21 are enrolled in college
(B) The percentage of women between twenty and
twenty-five who graduated from college - conclusion mentions nothing about graduation
(C) The percentage of women who, after attending
college, entered highly paid professions - conclusion mentions nothing about post graduation careers
(D) The percentage of men between twenty and
twenty-one who were enrolled in college -
YES! If you know about the percentage of men 20-21 enrolled in college, you can see if the proportion of women actually increased. i.e. - percentage increase can be due to population increase while proportion can stay the same - 15% more women entered college in 2007 due to population increase (while the proportion of women stayed at 30%)
(E) The percentage of men who graduated from high
school - only cares about college

I was stucked between A and D. and finally i picked A because if we know the percentage of women between twenty and twenty-one who were not enrolled in college of the years 1959 and 1981 and if the pertange of women not enrolled in the college in 1959 is higher than percentage of women not enrolled in the college in 1981 then we can conclude that women participation has increased between 1959-81.

D it is.
To compare the two percentages of women for the 2 years, we need the other gender enrolled to evaluate the percentage of women from the total enrolled. It is then that we say for sure that the percentage of women enrolled actually increased.

It is my understanding that the answer has to include something about men. The proportion of women here refers to : women /(women+men), where women +men are the students. There are two ways this proportion can increase:
1) number of women increases more than number of men
2) number of men decreases while number of women remains the same, increases, or decreases less then men
Therefore, it would be useful to determine how many men graduate from hight school, since graduating from highschool is a prerequisite for higher education.
I fell for the trap as well it seems. But clearly, D seems a better answers now that I look at it.

useful to compare 1959 and 1981 with regard to
which of the following characteristics?
(A) The percentage of women between twenty and
twenty-one who were not enrolled in college
- doesn't add anything to already available data
(B) The percentage of women between twenty and
twenty-five who graduated from college
- irrelevant
(C) The percentage of women who, after attending
college, entered highly paid professions
-irrelevant
(D) The percentage of men between twenty and
twenty-one who were enrolled in college
-If the percentage of men dropped, then it implies that the claim is right. However, if it did not drop or if it went up, then it might be that the number of such programs has increased over the decades. This is my choice
(E) The percentage of men who graduated from high
school
-irrelevant

D it is...
By comparing the number of men enrolled in the college in 20-21 age group we will have a better picture about the claim.
