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 said to emulate the legendary champion, Byron Nelson. Ten randomly selected balls of two brands are tested and the overall dice measured. Assume the data are normally distributed. The data follow: Brand 2 Brand 1 271 287 287 271 260 265 283 271 279 275 263 267 276 264 273 281 271 270 263 268 (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 interval on a₁/a₂. Round your answer to three decimal places (e.g. 98.765). 0₂
