14. Do Bednets Reduce Malaria? In a randomized controlled trial in Kenya, insecticidetreated bednets were tested as a way to reduce malaria. Among 343 infants who used the bednets, 15 developed malaria. Among 294 infants not using bednets, 27 developed malaria (based on data from “Sustainability of Reductions in Malaria Transmission and Infant Mortality in Western Kenya with Use of Insecticide-Treated Bednets,”

by Lindblade et al., Journal of the American Medical Association, Vol. 291, No. 21).

Use a 0.01 significance level to test the claim that the incidence of malaria is lower for infants who use the bednets. Do the bednets appear to be effective?
