echinacea, 42 of the 48 subjects treated with echinacea developed thinovirus infections. In a placebo group. 97 of the 113 subjects developed thinovirus an effect on thinovirus infections. Complete parts (a) through (c) below. and the second sample to be the sample of subjects treated with a placebo. What are the null and alternative hypotheses for the hypothesis test? OC. Ho P*P2 B. Ho P1 P2 Hy P = P2 HP: <P2 OF HO P2P2 DE. Ho P, SP2 Hy PP2 HP:7P2
GEDO P-value (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test? The P-value is the significance level of a =0.05. So the null hypothesis. There sufficient evidence to support the b. Test the daim by constructing an appropriate confidence interval. The 95% confidence interval is < (P1-P2) O (Round to three decimal places as needed) What is the conclusion based on the confidence interval? Because the confidence interval limits appear to be a significant difference between the two proportions. There c. Based on the results, does echinacea appear to have any effect on the infection rate? 0, there O A. Echinacea does appear to have a significant effect on the infection rate. There is evidence that it increases the infection rate
thesis. There sufficient evidence to support the claim that echinacea treatment has an effect nificant difference between the two proportions. There evidence to support the claim that echinacea treatment has an effect ce that it increases the infection rate
The P-value is the significance level of a=0.05, so the null hypothesis. There sufficient evidence to support the claim tha b. Test the claim by constructing an appropriate confidence interval o )-O (Round to three decimal places as needed.) What is the conclusion based on the confidence interval? Because the confidence interval limits 0, there appear to be a significant difference between the two proportions. There c. Based on the results, does echinacea appear to have any effect on the infection rate? O A. Echinacea does appear to have a significant effect on the infection rate. There is evidence that it increases the infection rate OB. Echinacea does appear to have a significant effect on the infection rate There is evidence that it lowers the infection rate OC. Echinacea does not appear to have a significant effect on the infection rate OD. The results are inconclusive,
