Since an instant replay system for tennis was introduced at a major tournament, men challenged 1419 referee calls, with the result that 423 of the calls were overturned. Women challenged 750 referee calls, and 226 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 = P2 OB. 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 # P2 OF. HO: P1 =P2 Hy: P1 = P2 Hy : P1 = P2 Hy: P1 = P2 Identify the test statistic. z= 'Round to two decimal places as needed.) Identify the P-value less than reject P-value = (Round to three decimal places as needed.) greater than fail to reject 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. include does not is sufficient The 99% confidence interval is = (P1 -P2) H2 The test statistic, t, is . (Round to two decimal places as needed.) The P-value is . (Round to three decimal places as needed.) State the conclusion for the test. O A. Reject the null hypothesis. There is sufficient evidence to support the claim that men have a higher mean body temperature than women. O B. Reject the null hypothesis. There is not sufficient evidence to support the claim that men have a higher mean body temperature than women. O C. Fail to reject the null hypothesis. There is not sufficient evidence to support the claim that men have a higher mean body temperature than women. O D. Fail to reject the null hypothesis. There is sufficient evidence to support the claim that men have a higher mean body temperature than women b. Construct a confidence interval suitable for testing the claim that men have a higher mean body temperature than women.
