Since an instant replay system for tennis was introduced at a major tournament, men challenged 1425 referee calls with the results that 412 of the calls were overturned. women challenged 739 referee calls, and 221 of the calls were overturned. use a 0.05 significance level to test the claim that men and women have equal success in challenging calls. test the claim using a hypothesis test. consider the first sample to be the sample of male tennis players who challenge referee calls and the second sample to be the sample of female tennis players that challenged referee calls. what are the null and alternative hypotheses for the hypothesis test.
