In a randomized controlled trial, insecticide-treated bednets were tested as a way to reduce malaria. Among 341 infants using bednets, 15 developed malaria. Among 294 infants not using bednets, 32 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: -0.0648553 99% upper bound for difference:-0.01 001708 Test for difference-0 (vs

Explanation / Answer
