The overall distance traveled by a golf ball is tested by hitting the ball with Iron Byron, a mechanical golfer with a swing that is sa emulate the legendary champion, Byron Nelson. Ten randomly selected balls of two brands are tested and the overall distance measured. Assume the data are normally distributed. The data follow: Brand 1 Brand 2 266 280 287 271 264 283 260 265 283 271 273 281 279 275 271 270 263 267 263 268 i (a) Is there evidence to show that there is a difference in the variance of the brands? Use a = 0.05. (b) Calculate a 95% two-sided confidence VI 52 VI interval on 0₁/0₂. Round your answer to three decimal places (e.g. 98.765). i
