Since an instant replay system for tennis was introduced at a major tournament, men challenged 1402 referee calls, with the result that 418 of the calls were overturned. Women challenged 765 referee calls, and 212 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 hypothesis test? female tennis players who challenged referee calls. What are the null and alternative hypotheses for the O A. Ho: P1 =P2 H: P P2 O D. Ho: P, 2 p2 H:P, *P2 OE. Ho: P, SP2 H: P1 P2 OF. Ho: P, #P2 H: P, "P2 Identify the test statistic. (Round to two decimal places as needed.) Identify the P-value. P-value =O (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test? The P-value is V the significance level of a = 0.01, so the null hypothesis. There v evidence warrant rejection of the claim that women and men have equal success in challenging calls. b. Test the claim by constructing an appropriate confidence interval. The 99% confidence interval is < (P, - P2)
