Since an instant replay system for tennis was introduced at a major tournament, men challenged 1405 referee calls, with the result that 417 of the calls were overturned. Women challenged 740 referee calls, and 211 of the calls were overturned. Use a 0.05 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. challenged referee calls. What are the null and alternative hypotheses for the hypothesis test? A. H0:p1=p2 B. H0:p1=p2 C. H0:p1=p2 H1:p1=p2 H1:p1=p2 H1:p1<p2 D. H0:p1≤p2 E. H0:p1≥p2 F. H0:p1=p2 H1:p1=p2 H1:p1=p2 H1:p1>p2 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?
that women and men have equal success in challenging calls. b. Test the claim by constructing an appropriate confidence interval. The 95% confidence interval is <(p1−p2)< (Round to three decimal places as needed.) What is the conclusion based on the confidence interval? 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 may have equal success in challenging calls? speculate that women have more success. B. The confidence interval suggests that there is a significant difference between the success of men and in in challenging calls in speculate that men have more success. C. The confidence interval suggests that there is no significant difference between the success of men and women in challenging calls. D. There is not enough information to reach a conclusion.
