Since an instant replay system for tennis was introduced at a major​ tournament, men challenged 1437referee​ calls, with the result that 426

of the calls were overturned. Women challenged 752 referee​ calls, and 225 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?

Identify the test statistic.
