Given that in a randomized controlled trial in Kenya, insecticide treated 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.
H0: p1=p2
H1: p1 <p2
(one tailed test)
p1 = 15/343:p2 =27/294:
Difference 4.813 %
95% CI 0.9160% to 9.0217%
Chi-squared 5.947
DF 1
Significance level P = 0.0073
Since p <0.01 we reject null hypothesis.
