Chapter 15, Problem 23PS

The file FTMBA contains a sample of 2012 top-ranked full-time MBA programs. Variables included are mean starting salary upon graduation $\left(\text{\$}\right),$ percent of students with job offers within three months of graduation, program cost $\left(\text{\$}\right),$ and total number of students per program. (Data extracted from buswk.co/25d1ZC.) Develop the most appropriate multiple regression model to predict the mean starting salary upon graduation. Be sure to include a thorough residual and influence analysis. In addition, provide a detailed explanation of the results, including a comparison of the most appropriate multiple regression model to the best simple linear regression model.
