Since an instant replay system for tennis was introduced at a major tournament, men challenged 1421 referee calls, with the result that 430 of the calls were overturned. Women challenged 745 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. a. Identify the test statistic. z= (Round to two decimal places as needed.) b. Identify the P-value. P-value= (Round to three decimal places as needed.) c. Test the claim by constructing an appropriate confidence interval. The 99% confidence interval is
