Question 2 The National Golf Association's consumer advocacy group wishes to compare the variabilities in durability of two brands of golf balls: Champ golf balls and Master golf balls. The advocacy group randomly selects 10 balls of each brand and places each ball into a machine that exerts the force produced by a 250-yard drive. The number of simulated drives needed to crack or chip each ball is recorded, and the results are given below. DS GolfBrands Champ Golf Balls Master Golf Balls 334 301 307 298 364 270 290 302 350 348 396 342 359 327 355 315 305 325 331 325 Assuming normality, test to see if the variabilities in durability differ for the two brands at the .10, .05, and .01 levels of significance. What do you conclude?
