Predicting College GPA

A college counselor knows there is a negative correlation between the number hours of TV watched per week and GPA. Here's the supporting data:

Tv in Hours Per Week	GPA
14	3.1
10	2.4
20	2.0
7	3.8
25	2.2
9	3.4
15	2.9
13	3.2
4	3.7
21	3.5

4. If a student is watching 18 hours of TV per week, what is his or her projected GPA?

5. If a student is watching 32 hours of TV per week, what is his or her projected GPA?

6. What is the Standardized Regression Coefficient for these data?
