Use the expression in the accompanying discussion of sample size to find the size of each sample if you want to estimate the difference between proportions of men and women whoown smartphones. Assume that you want 99% confidence that your error is no more than 0.03.iClick the icon to view the discussion of sample size.The sample should include men and(Type whole numbers.)women.Sample size discussionThe sample size needed to estimate the difference between two populationproportions to within a margin of error E with a confidence level of 1 - α can befound by using the following expression:E=Zx/2Replace n₁ and n₂ by n in the preceding formula (assuming that both sampleshave the same size) and replace each of p₁, 91, P2, and q2 by 0.5 (because theirvalues are not known). Solving for n results in this expression:n=P191 P292n₁n₂zα/22E²PrintDoneX
