Consider the enrollment data for Business Week's top U.S. graduate business programs in the file P10_21.xlsx. Use the data in the MBA Data sheet to estimate a multiple regression equation to assess whether there is a relationship between the total number of full-time students (Enrollment) and the following explanatory variables:
(a) the proportion of female students,
(b) the proportion of minority students, and
(c) the proportion of international students enrolled at these business schools.
a. Interpret the coefficients of the estimated regression equation. Do any of these results surprise you? Explain.
b. How well does the estimated regression equation fit the given data?
