At the bowling alley, Alyssa records each bowler’s score and the weight of the bowling ball
they used. She limits her study to bowlers with 14-pound balls and 16-pound balls. At the

average score than bowlers who used the lighter bowling balls.

(b) Based on this study, should you conclude that using a heavier ball makes you achieve a
higher score? Explain your reasoning.
