According to a dietary study, a high sodium intake may be related to ulcers, stomach cancer, and migraine
headaches. The human requirement for salt is only 220 milligrams per day, which is surpassed in most single
servings of ready-to-eat cereals. If a random sample of 15 similar servings of certain cereal has a mean sodium
content of 244 milligrams and a standard deviation of 24.5 milligrams, does this suggest at the 0.05 level of
significance that the average sodium content for a single serving of such cereal is greater than 220 milligrams?
