What can predict how much a motion picture will make? Data on a number of recent releases that includes the Gross ($M), the Budget ($M), the Run Time (minutes), and the average number of Stars awarded by reviewers was collect regression model was created to predict Gross. Use the computer output given below to complete parts a and b. Dependent variable is: Gross R squared = 42.3%, R squared (adjusted) = 40.8% s = 46.03 with 120 -4 = 116 degrees of freedom Variable Coef SE(Coef) t-ratio P-value Intercept - 22.1081 24.42 - 0.91 0.3647 Budget 1.13691 0. 12633 9.00 0.0000 Stars 25.0311 5.857 4.27 0.0000 Run Time - 0.406589 0.2475 - 1.64 0.1037 a) Write the multiple regression equation. Gross = () + Budget + (Stars + (Run Time (Use.integers or decimals for any numbers in the expression. Do not round.) b) What is the interpretation of the coefficient of Budget in this regression model? After allowing for the effect(s) of each increase of 1 on is associated with an average increase of about Von V
