In your work for a national health organization, you are aware that for prior studies of the amount of sodium in a certain brand of cereal is 205 milligrams. Based upon your sample of 25 servings you find a mean sodium content of 218 milligrams, with a standard deviation of 15 milligrams. You want to test the hypothesis that the mean amount of sodium in this brand of cereal differs from the stated mean of 205 milligrams. For an α = .02 significance level, determine the Critical Value(s) that separate(s) the region of retention from the region(s) of rejection.
