Sample Average Proportion Malaria Rates for Children by Group Assignment

Experimental - n=100,  sample proportion that contracted malaria = .30

Control - n=100, sample proportion that contracted malaria = .45 

a) Provide an estimate of the impact on having a family provided with an insecticide treated mosquito net on the incidence of malaria among children residing in the Nyanza province of Kenya.

b) Construct a 90% confidence interval for the impact of providing villages in the Nyanza Province of Kenya with insecticide-treated mosquito nets on the incidence of annual malaria contraction among children.

c) What is the (population) parameter of interest in this study? In other words, what are we interested to learn?

d) What would be the appropriate hypothesis to test if you would like to determine whether providing villages with insecticide-treated mosquito netting has no effect of malaria among children in the Nyanza province?

e) What is the sample statistics we are going to use in this hypothesis test? What is the distribution under the null hypothesis?

f) Using a significance level of 0.05, what can you conclude from the hypothesis test?
