In a sample of 1392 mosquitoes
In a sample of 1392 mosquitoes trapped in a region, 1173 testedpositive for a certain disease. In a sample of 1457 mosquitoestrapped in a different region, 1196 tested positive for thedisease. Compute the test statistic for a hypothesis test tocompare the population proportions of mosquitoes in the regionsthat tested positive for the disease. Assume that the conditionsfor a hypothesis test for the difference between the populationproportions are met. Round your answer to two decimal places.
Answer:
Let denote the proportion of mosquitoes tested positive for a certaindisease in two regions respectively.
