Rhino viruses typically cause common colds. in a test of the effectiveness of echinacea, 46 of the 51 subjects treated with echinacea developed rhinovirus infections. in a placebo group, 82 of the 95 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. 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 arc the null and alternative hypotheses for the hypothesis test? identify the test statistic. - (round to two decimal places as needed.) identify the p-valuc. (round to three decimal places as needed.) what is the conclusion based on the hypothesis test? what is the conclusion base
