Question 1: A consumer group wished to compare the driving distances of three bands of golf balls. Eight balls of each brand were hit using a mechanical driver. The distance (in yards) travelled by each ball was recorded, yielding the following: Brand A Brand B Brand C 251.1 248.7 251.0 250.9 251.2 251.1 248.8 250.9 250.8 253.3 251.8 252.2 248.6 250.4 255.2 254.6 261.1 261.6 263.9 263.3 257.9 256.7 263.1 258.7 Test at = 0.05 if there is sufficient evidence to indicate that the mean driving distance differs for the three brands.
