Rhino viruses typically cause common colds. In a test of the effectiveness of echinacea, 47 of the 52 subjects treated with echinacea developed rhinovirus infections. In a placebo group, 99 of the 114 subjects developed rhinovirus infection a 0.01 significance level to test the claim that echinacea has an effect on rhinovirus infections. Complete parts (a) through (c) below. 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: Pi Z P2 H,: P1 * P2 O B. Ho: P1 =P2 H: P, P2 Identify the test statistic. (Round to two decimal places as needed.) Identify the P-value. P-value = (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test? V the null hypothesis. There V sufficient evidence to support the claim that echinacea treatment has an effect. The P-value is V the significance level of a =0.01, so b. Test the claim by constructing an appropriate confidence interval. The 99% confidence interval is< (P, -P2)
