Since an instant replay system for tennis was introduced at a major tournament, men challenged 1413 referee calls, with the result that 414 of the calls were overturned. Women challenged 754 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. 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? O B. Ho: P, = P2 O A. Ho: P1 2 P2 H,:P, #P2 OC. Ho: P, SP2 H: P, #P2 H: P, >P2 O D. Ho: P1 = P2 H:P, *P2 O E.

Since an instant replay system for tennis was introduced at a major tournament, men challenged 1413 referee calls, with the result that 414 of the calls were overturned. Women challenged 754 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. 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? А. Но: Р1 2 Р2 H4: P1 # P2 B. Ho: P1 = P2 C. Ho: P1 SP2 H1: P1> P2 H1: P1 # P2 O D. Ho: P1 = P2 H4: P1 #P2 E. Ho: P1 # P2 H1: P1 = P2 F. Ho: P1 = P2 H1: P1 <P2 Identify the test statistic. (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? The P-value is the significance level of a = 0.05, so 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 95% 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
