In a statistics course, a linear regression equation was computed to predict the final-exam score from the score on the first test. The equation was = 10 + 0.9x where y is the final-exam score and x is the score on the first test. Carla scored 95 on the first test. What is the predicted value of her score on the final exam? (a) 85.5 (b) 90 (c) 95

Caution: Once you do a linear regression, there is a set of residuals that are stored automatically in the list resid on your calculator. It gets replaced if you run a linear regression on another set of data. You cannot save the residual list. You must run the correct regression before getting the residual plots. 22.
