How do I solve this?

Rhino viruses typically cause common colds. In a test of the effectiveness of echinacea, 35 of the 42 subjects treated with echinacea developed rhinovirus infections. In a placebo group, 94 of the 108 subjects developed rhinovirus infections. Use a 0.05 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 SP2 OB. HO: P1 # P2 H1: P1 = P2 H1: P1 > P2 Hy: P1 = P2 OF. Ho: P1 2 P2 O D. Ho: P1 = P2 E. HO: P1 = P2 H1 : P1 # P2 Hy: P1
