Since an instant replay system for tennis was introduced at a major tournament, men challenged 1383 referee calls, with the result that 418 of the calls were overtumed. Women challenged 764 referee calls, and 220 of the calls were overtumed. Use a 0.05 significance level to test the olaim that men and women have equal success in challenging calls. Complete parts (a) through (c) below a. Test the olaim using a hypothesis test Consider the fist 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 cals. What are the null and alternative hypotheses for the hypothesis test? OB. Hg PP OC. Hg P"P OA Hg: P SP Hy: PP2 OD. Hg: P2 p2 H: PP2 H P

Question
Since an instant replay system for tennis was introduced at a major tournament, men challenged 1383 referee calls, with the result that 416 of the calls were overtumed. Women challenged 764 referee calls, and 220 of the calls were overtumed. 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. 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? OC. Họ P"P2 OB. Ho P-P2 H: PP2 OA. Ho P SPP2 H1: PP2 H: P <P2 OD.

There V 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 05% confidence interval is< (P1- P2) <O (Round to three decimal places as needed. What is the conclusion based on the confidence interval?
