3.    Find the probability that a randomly selected university will have an admissions rate below 60% given that it is a private institution.

Section 4 Confidence Intervals:  In this section you will need to construct 95% Confidence intervals of the mean and variance of all the numerical (quantitative) data.  For each please interpret the confidence interval and explain any surprising results. 

Section 5 Hypothesis Testing: In this section you will make some hypotheses about the data and then use what we learned in lecture/homework to test these hypotheses.
