EXAMPLE 11.14 Test for Movie Revenue Model

CASE 11.2 Example 11.13 (pages 552–553) gives the results of multiple regression analysis for predicting U.S. box office revenue. The statistic is 32.71. The degrees of freedom appear in the ANOVA table. They are 3 and 39. The software packages (see Figure 11.11) report the -value in different forms: Excel, 9.73E-11; Minitab, 0.000; and JMP, <0.0001. Based on all the output, we would report the results as follows: a movie’s budget, opening-weekend revenue, and opening-weekend theater count contain information that can be used to predict the movie’s total U.S. box office revenue (, and 39, ).
