Question
In order to compare the durability of four different brands of golf balls (ALPHA, BEST, CENTURY, and DIVOT), the National
Golf Association randomly selects 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. Use a significance level of 0.05
to conduct all hypothesis tests and construct confidence intervals.
