Rhino viruses typically cause common colds. In a test of the effectiveness of echinacea, 39 of the 44 subjects treated with echinacea developed rhinovirus infections. In a placebo group, 95 of the 112 subjects developed rhinovirus infections. Use a 0.05 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.
