A Hollywood studio believes that a movie that is considered a drama will draw a larger crowd on average than a movie that is considered a comedy. To test this theory, the studio randomly selects several movies that are classified as dramas and several movies that are classified as comedies and determines the box office revenue for each movie. The results of the survey are as follows. Assume that the population variances are approximately equal. Box Office Revenues (Millions of Dollars) n x S Drama 14 150 50 Comedy 16 120 10 Copy Data Calculate a 99 % confidence interval for the difference in mean revenue at the box office for drama and comedy movies. Let dramas be Population 1 and comedies be Population 2. Write your answer using interval notation and round the interval endpoints to two decimal places.
▾ Part 1 of 4 A beverage company has two bottling plants in different parts of the world. To insure uniformity in their product, the variances of the weights of the bottles at the two plants should be equal. But Parvez, the company's vice president of quality assurance, suspects that the variance at bottling plant A is less than the variance at bottling plant B. To test his suspicions, Parvez samples 34 bottles from bottling plant A and 34 bottles from bottling plant B, with the following results (in ounces): Bottling Plant A: 12.4, 12.5, 12, 13.3, 11.6, 11.9, 12.7, 13.1, 14.1, 12.4, 12, 12.4, 12.9, 12.2, 12.6, 12.7, 12.3, 12.5, 12.7, 12.7, 12.8, 12.8, 13.6, 11.4, 12.4, 12.5, 13.1, 12.6, 13.1, 12.6, 12.2, 12.9, 12.7, 13.5 Bottling Plant B: 12.1, 12.3, 12.2, 12.2, 12.4, 12.2, 12.2, 12.5, 12.4, 13.1, 12.2, 12.6, 12.1, 11.9, 13.2, 11.2, 12.9, 13.1, 11.6, 13.5, 12, 12.3, 12.4, 13, 12.9, 12.9, 12.4, 13.2, 12.5, 12.9, 13, 13.1, 12.3, 11.6 Perform a hypothesis test using a 7% level of…
