According to Dietary Goals for the United States (1977), high sodium intake may be related to ulcers, stomach cancer, and migraine headaches. The human requirement for salt is only 220 miligrams per day, which is surpassed in most single servings of ready-to-eat cereals. If a random sample of 20 similar servings of Special K has a mean sodium content of 224 miligrams of sodium and a standard deviation of 24.5 miligrams, does this suggest at the 0.05 level of significance that the average sodium content for a single servings of Special K is greater than 220 miligrams? Assume the distribution of sodium contents to be normal.
