Since an instant replay system for tennis was introduced at a major tournament, men challenged 1397 referee calls, with the result that 421 of the calls were overturned. Women challenged 740 referee calls, and 229 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. Identify the test statistic. 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 significance level of a = 0.01, so The P-value is the null hypothesis. There evidence to 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< (P1 - P2) <]. (Round to three decimal places as needed.) What is the conclusion based on the confidence interval? 0, there Because the confidence interval limits appear to be a significant difference between the two proportions. There in challenging calls. evidence to warrant rejection of the claim that men and women have equal success 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.
