Rhino viruses typically cause common colds. In a test of the effectiveness of echinacea, 37 of the 43 subjects treated with echinacea developed rhinovirus infections. In a placebo group, 89 of the 106 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? OA. Ho: P₁ SP2 H₁: P₁ P2 O D. Ho: P₁ P2 H₁: P₁ P2 OB. Ho: P₁ = P2 H₁: P₁ P2 (...) O E. Ho: P₁ = P2 H₁: P₁ P2 OC. Ho: P1 H₁: P₁ P2 P2 OF. Ho: P₁ P2 H₁: P₁ = P2
