Clearly one would assume that private colleges and universities would have a higher annual total cost as tuition is higher at private institutions. Construct a 95% confidence interval to estimate how much more it would cost annually to attend a private institution and interpret these values in a clear sentence. This is asking you to construct a confidence interval estimate of the difference in mean tuition.
1) Please perform an F-test for Equal Variances to determine which Two-sample t-test and SE to use. Copy and paste the necessary F-test output below and clearly state your conclusion
2) Then perform the appropriate two-sample t-test to get the necessary descriptive statistics to construct the confidence interval. Show all necessary work and/or paste your Excel output.
