A. is there a connection between the graduation rate and the % of alumni that give back? Create a regression model and explain the information.

B. Make a regression model utilizing all the independent variables (graduation rate, percentage of classes with class size below 25, faculty to student ratio) while having the same dependent variable as in the previous question.

C. Based on the results in (A) and (B), do you believe another regression model may be more appropriate? Estimate this model, and infer your results.
