Exercise 51 examined the relationship between the tuition charged by states for four-year colleges and universities compared to the tuition for twoyear colleges. Now, examine the relationship between private and public four-year colleges and universities in the states.

c) What is the regression equation for predicting the tuition at a four-year private institution from the tuition at a four-year public institution in the same state?
d) Is a linear model appropriate?
e) Interpret the regression equation. How much more is the tuition for four-year private institutions compared to four-year public institutions in the same state according to this model?
