Question:

Exercise 12-2 presented a regression model to predict final grade from two hourly tests.

4871.0 (X'y) =| 426011.0 367576.5

(a) Test the hypotheses that each of the slopes is zero.

(b) What is the value of R² for this model?

(d) Do you believe that the professor can predict the final grade well enough from the two hourly tests to consider not giving the final exam? Explain.
