Question

Read the following prompt and complete the subquestions 6.a, 6.b, 6.c, and 6.d.

Question 6 Background : Echinacea for Colds? Rhinoviruses typically cause common colds. In order to test the effectiveness of echinacea, participating subjects were randomly divided into two groups: subjects in group 1 were treated with echinacea and subjects in group 2 received a placebo. For each subject, we recorded whether or not they developed rhinovirus infections. The 90% confidence interval for the difference in population proportions between all subjects who would develop rhinovirus infections after being treated with echinacea vs. all subjects who would develop rhinovirus infections after being treated with placebo is (-0.1193, 0.1884). Question 6 Subquestions 6.a What is the estimate for the difference in the two population proportions? P1-P2 = 0.03455 P1-P2 = 0.15385 O P1-P2 = 0.0691

6.b Provide the interpretation of this 90% confidence interval, in the context of the problem. No answer entered. Click above to enter an answer. 6.c In your own words, describe what the "margin of error" is, and describe its relationship to the "standard error". No answer entered. Click above to enter an answer. 6.d Based on this interval, could you conclude (at a corresponding 10% level) there is a significant difference between all subjects in the two treatment groups in terms of the population rates who who would develop rhinovirus infections?
