Answer #1

The answer is:

Since we are interested in knowing whether Snow college students or SLCC students make more money 20 years after graduation, therefore we this problem relates to mean and not proportion. Money is a quantitative variable, and the two samples for Snow college students and SLCC students will be independent. Hence the only logical choice is the 2 sample t-test.
