In a test of the effectiveness of echinacea, 36 of the 42 subjects treated with echinacea developed rhinovirus infections. In a placebo group, 90 of the 104 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. The P-value is greater than the significance level of a 0.01, so fail to reject the null hypothesis. There is not sufficient evidence to support the claim that echinacea treatment has an effect. b. Test the claim by constructing an appropriate confidence interval The 99% confidence interval is -0.172 (p1 p2) 55 (Round to three decimal places as needed.) What is the conclusion based on the confidence interval? Because the confidence interval limits Y 0, there appear to be a significant difference between the two proportions. There evidence to support the claim that echinacea treatment has an effect.
