Basic Computation: Sample size Suppose x has a mound-shaped distribution with = 3.
(a) Find the minimal sample size required so that for a 95% confidence interval, the maximal margin of error is E = 0.4.
(b) Check Requirements Based on this sample size, can we assume that the
distribution is approximately normal Explain.
