Please find the test statistic, p value and the 95% confidence interval. Thank you!

Rhino viruses typically cause common colds. In a test of the effectiveness of echinacea, 38 of the 45 subjects treated with echinacea developed rhinovirus infections. In a placebo group, 98 of the 113 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 SP2 O A. Ho: P1 # P2 O B. Ho: P1 2 P2 H1 : P1 * P2 Hy: P1 = P2 H1 : P1 = P2 O E. Ho: P1 = P2 OF. Ho: P1 = P2 O D. Ho: P1 = P2 H1: P1
