Assume that we need to estimate the mean of a normally-distributed population with great accuracy. Specifically, for significance level α = .01, we wish to place a confidence interval around μ such that the width of the interval is no larger than .1. Assume that the variance of the population is known to be 0.04. How large must the sample size be to assure that the width of the confidence interval is no larger than 0.1?
