What can predict how much a motion picture will make? Data on a number of recent releases that includes the Gross ($M), the Budget (SM), the Run Time (minutes), and the average number of Stars awarded by reviewers was collected and a regression model was created to predict Gross. Use the computer output given below to complete parts a through d. Dependent variable is: Gross R squared = 41.6%, R squared (adjusted) = 40.1% s=46.68 with 120-4-116 degrees of freedom Variable Coef Intercept - 22.3182 Budget Stars Run Time 1.13467 23.2802 -0.411359 O A.
