Re: DI Set #6-fifteen private colleges is represented by circle [#permalink]

For question 1, the black dots (the college's investment income) not always DECREASE as student enrollment INCREASES. Between (15 to 19) and (20 to 23) they increase, so we cannot say that investment income is negatively correlated with student enrollment. Almost half of the numbers are positively correlated. In fact, the correlation is not linear and decreasing always. Therefore, in question one number two(II) is not correct.

For question 2, shouldn't the number of students be 40,000, as opposed to 4,000?

for question 2 option b is right.....because no. of student approx. is 32500 and total investment is around 840 million.
investment per student= 840 million/32500=25846.15385 and this round up to 28000(b)

Carcass - is question 1 answers correct?
Option A:
Positive correlation - as students increase tuition income increase - As you can see that is not the the case always with respect to previous years
Option B:
Negative correlation - As students increase, investment income decreases - this is also not true. There is less correlation wrt to option A.

IMO choice C is correct

Could you please evaluate my reasoning, am I missing the obvious here?

Thanks
