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
