In a randomized controlled trial, insecticide-treated bednets were tested as a way to reduce malaria. Among 324 infants using bednets, 15 developed malaria. Among 298 infants not using bednets, 27 developed malaria. Use a 0.05 significance level to test the claim that the incidence of malaria is lower for infants using bednets. a. Test the claim using a hypothesis test. b. Test the claim by constructing an appropriate confidence interval. c. Based on the results, do the bednets appear to be effective? O A. Hg: P12 P2 H1: P1 < P2 B. Ho: P1 = P2 H1: P1 < P2 O C. Ho: P1 = P2 H: P1 # P2 OF. Ho: P, #P2 H1: P1 = P2 O D. Ho: P1 = P2 H1: P1 > P2 O E. Ho: P1 S P2 H1: P1 > P2 Identify the test statistic. (Round to two decimal places as needed.)
