Question

In a randomized controlled trial, insecticide-treated bednets were tested as a way to reduce malaria. Among 334 infants using bednets, 18 developed malaria. Among 296 infants not using bednets, 34 developed malaria. Use a 0.05 significance level to test the claim that the incidence of malaria is lower for infants using bednets. Do the bednets appear to beeffective? Conduct the hypothesis test by using the results from the given display.

Explanation / Answer

Answer

D) Ho : p1 = p2 vs H1 : p1 < p2

Value of Test Statistics is - 2.78

P Value = 0.003

Conclusion :- P value < Significance Level (0.05) we reject null hypothesis, There is sufficient evidence to suport the claim that incidence of malaria is lower for infants using bednets.
