Rhino viruses typically cause common colds. In a test of the effectiveness of echinacea, 40 of the 46 subjects treated with echinacea developed rhinovirus infections. In a placebo group, 94 of the 110 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 A. Ho:P SP2 H4: P1 P2 OD. Ho: P1 = P2 HP1 P2 OB. Ho: P12 P2 H:P*P2 O E. Ho: P1 = P2 H: P1 P2 C. Ho: P4 # P2 H:P4 = P2 OF.
