Rhino viruses typically cause common colds. In a test of the effectiveness of echinacea, 36 of the 42 subjects treated with echinacea developed rhinovirus infections. In a placebo group, 94 of the 107 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. Identify the test statistic. z=enter your response here (Round to two decimal places as needed.) Identify the P-value. P-value=enter your response here (Round to three decimal places as needed.) b. Test the claim by constructing an appropriate confidence interval. The 99% confidence interval is enter your response here
