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 distance measured. assume that the variances are equal. the data follow: brand 1: 277 278 287 271 283 271 279 275 263 267 brand 2: 262 248 260 265 273 281 271 270 263 268 is there evidence to show that there is a difference in the mean overall distance of brands?
