Reino viruses typically cause common colds, in a test of the effectiveness of echinacea, 47 of the 52 subjects treated with echinacea developed thinovirus infections. In a placebo group, 87 of the 101 subjects developed mhinovirus infections. Use a 001 significance level to test the claim that echinacea has an effect on chinovirus infections Complete parts (a) through (6) below b. Test the claim by constructing an appropriate confidence interval The 99% confidence interval is (-) Round to three decimal places as needed.) What is the conclusion based on the confidence interval? 0, there Because the confidence interval limits has an offoct e. Based on the results, doos echinacen appear to have any effect on the infection rate? COLD- appear to be a significant difference between the two proportions.
