In a randomized controlled trial, insecticide-treated bednets were tested as a way to reduce malaria. Among 349 infants using bednets, 22 developed malaria. Among 257 infants not using bednets, 23 developed malaria. Use a 0.01 significance level to test the claim that the incidence of malaria is lower for infants using bednets. Do the bednets appear to be effective? Conduct the hypothesis test by using the results from the given display. Difference = p(1) - p(2) Estimate for difference: - 0.0264569 99% upper bound for difference: 0.03034574 Test for difference 0 (vs <0): Z= - 1.23 P-Value = 0.110 OD. Ho: P1 = P2 H: P, #P2 O F. Ho: P1 = P2 O E. Ho: P1 SP2 H: P1 > P2 H,: P1
