In a randomized controlled trial in Kenya, insecticidetreated bednets were tested as a way to reduce malaria. Among 343 infants using bednets, 15 developed malaria. Among 294 infants not using bednets, 27 developed malaria. We want to use a 0.05
significance level to test the claim that the incidence of malaria is lower for infants using bed nets. Assume test statistic is -2.44.
Calculate Critical value; do you reject or support the claim.
