# Question

Consider the null hypothesis H0: µ = 625. Suppose that a random sample of 29 observations is taken from a normally distributed population with σ = 32. Using a significance level of .01, show the rejection and non-rejection regions on the sampling distribution curve of the sample mean and find the critical value(s) of z when the alternative hypothesis is as follows.
a. H1: µ = 625
b. H1: µ > 625
c. H1: µ < 625
