Question

Since an instant replay system for tennis was introduced at a major tournament, men challenged

1407

referee calls, with the result that

425

of the calls were overturned. Women challenged

771

referee calls, and

213

of the calls were overturned. Use a

0.01

significance level to test the claim that men and women have equal success in challenging calls. Complete parts (a) through (c) below.

a. Test the claim using a hypothesis test.

Consider the first sample to be the sample of male tennis players who challenged referee calls and the second sample to be the sample of female tennis players who challenged referee calls. What are the null and alternative hypotheses for the hypothesis test?

The confidence interval suggests that there is a significant difference between the success of men and women in challenging calls. It is reasonable to speculate that men have more success.

The confidence interval suggests that there is no significant difference between the success of men and women in challenging calls.
