Q4 The overall distance traveled by a golf ball is tested by hitting the ball with iron. Eight randomly selected balls of two different brands are tested and the overall distance measured. The data are as follow: Brand-1 275 286 287 271 283 279 263 267 P Brand-2 258 244 260 265 275/ 270, 263, 268 Assuming the population variance of both brands are equal, (i) Compute the sample mean and sample variance of each brand. (ii) Test the hypothesis that both brands of ball have equal mean overall distance at 5% level of significance. (iii) Construct a 95% confidence interval on the mean difference in overall distance for the two brands of golf balls. [2 IX IX

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.
