Graduation rate€”the percentage of entering freshmen attending full time and graduating within 5 years€”and what influences it have become a concern in U.S. colleges and universities. U.S. News and World Report€™s €œCollege Guide€ provides data on graduation rates for colleges and universities as a function of the percentage of freshmen in the top 10% of their high school class, total spending per student, and student-to-faculty ratio. A random sample of 10 universities gave the following data on student-to-faculty ratio (S/F ratio) and graduation rate (Grad rate).

Discuss what satisfying the assumptions for regression inferences would mean with student-to-faculty ratio as the predictor variable and graduation rate as the response variable.
