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 distance hit by the legendary champion Byron Nelson. Ten randomly selected balls of two different brands are tested and the overall distance measured. Brand 1: 275, 286, 287, 271, 283, 271, 279, 275, 263, 267 Brand 2: 258, 244, 260, 265, 273, 281, 271, 270, 263, 268 a) Is there evidence to support the claim that the standard deviation of overall distance is the same for both brands of balls (use α = 0.05)? b) Is there evidence to support the claim that the mean of the overall distance is the same for both brands of balls (use α = 0.05)?
