Women challenged 761 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? OB. Ho: P1 = P2 O C. Ho: P1 = P2 O A.

In a test of the effectiveness of echinacea, 45 of the 50 subjects treated with echinacea developed rhinovirus infections. In a placebo group, 87 of the 104 subjects developed rhinovirus infections. Use a 0.01 significance level to test the claim that echinacea has an effect on rhinovirus infections. Complete parts (a) through (c) below. a. Test the claim using a hypothesis test. Consider the first sample to be the sample of subjects treated with echinacea and the second sample to be the sample of subjects treated with a placebo. What are the null and alternative hypotheses for the hypothesis test? O C. Ho: P1 = P2 O A. Ho: P1 2 P2 O B. Ho: P1 SP2 H1 : P1 / P2 H1: P1 # P2 Hy : P1 > P2 O D. Ho: P1 # P2 O E. Ho: P1 = P2 OF.
