1. Develop and estimated simple linear regression model that can be used to predict the alumni giving rate, given the graduation rate.

2. Develop an estimated multiple linear regression model that could be used to predict the alumni giving rate using the graduation, % of Classes Under 20, and Student/Faculty Ratio as independent variables. 

3. Which of the 123 schools has the most (least) impressive giving rate? 

4. Consider a school that similar to Joseph’s university. Joseph’s University has 65% graduation rate and a student-faculty ration of 19:1, 37% of the classes have fewer than 20 students, 23% of the classes have more than 50 students, and have a freshman retention rate of 80%. Should Joseph’s university giving rate be greater or less than 8%?

5. What conclusions and recommendations can you derive from your analysis?

Variable	Description
ID	An identifier running from 1 to 123 (schools are listed in alphabetical order)
School	Name of the school
SFR	Student-to-faculty ratio
LT20	Percentage of classes with fewer than 20 students
GT50	Percentage of classes with greater than 50 students
GRAD	Average six-year graduation rate
FRR	Freshman retention rate
GIVE	Average alumni giving rate
