CALCULATION OF 95% CONFIDENCE INTERVAL FOR THE DIFFERENCE BETWEEN THE MEANS OF TWO VARIABLES The variables are from populations with normal distributions that have the same standard deviation (σ). To make the estimate, take the same number of samples from each population, calculate the mean for each sample, calculate the difference between those sample means, and then add or subtract the term that defines the confidence interval. If the width of the confidence interval should be less than 2 x σ, what is the minimum number of samples you should take from each population?
