Since an instant replay system for tennis was introduced at a major tournament, men challenged 1419 referee calls, with the result that 430 of the calls were overturned. Women challenged 769 referee calls, and 222 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 of female tennis players who challenged referee calls. What are the null and alternative hypotheses for the hypothesis test? O A. Ho: P1 2 P2 O B. Ho: P1 = P2 O C. Ho: P1 # P2 H1 : P1 # P2 H1 : P1 > P2 H1 : P1 = P2 O D. Ho: P1 = P2 OE. Ho: P1 SP2 OF. HO: P1 = P2 Hy : P1 # P2 Hy : P1 # P2 Hy : 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 = 0.01, 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 99% confidence interval is |
