A statistics professor has devised a diagnostic quiz, which,
when given during the first class, can accurately predict a
student’s performance on the final test. So far data are available
for 10 students, as follows:

a. Find the regression equation for predicting the final test
score from the quiz.

c. What final test score would be predicted for a student who
scored a 9 on the quiz?
