Since an instant replay system for tennis was introduced at a major tournament, men challenged 1420 referee calls, with the result that 417 of the calls were overturned. Women challenged 768 referee calls, and 214 of the calls were overturned. Use a 0.05 significance level to te 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? OC. Ho: P "P2 OB. Ho: P 2P2 H: P P2 H: P, P2

Z = (Round to two decimal places as needed.) Identify the P-value. P-value = (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test? V the null hypothesis. There ▼ the significance level of a = 0.01, so evidence to warrant rejection of the claim that women and men have equal success in challenging calls. The P-value is b. Test the claim by constructing an appropriate confidence interval. The 99% confidence interval is< (P1 - P2) <U. (Round to three decimal places as needed.) What is the conclusion based on the confidence interval? Because the confidence interval limits 0, there appear to be a significant difference between the two proportions. There evidence to warrant rejection of the claim that men and women have equal success in challenging calls. c. Based on the results, does it appear that men and women have equal success in challenging calls? O A. It appears that men and women have equal success in challenging calls. O B. It does not appear that men and women have equal success in challenging calls. Women have more success. OC. It does not appear that men and women have equal success in challenging calls. Men have more success. O D. The results are inconclusive.
