Let X be the mean of a random sample of size n from a N(μ,9) distribution.
a. Find n so that X −1< μ < X +1 is a confidence interval estimate of μ with a confidence level of at least 90%.
b.Find n so that X−e < μ < X+e is a confidence interval estimate of μ withaconfidence levelofatleast (1−α)⋅100%.
