Since an instant replay system for tennis was introduced at a major tournament, men challenged 1413 referee calls, with the result that 416 of the calls were overturned. Women challenged 776 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...
