According to a dietary study, high sodium intake may be related to ulcers, stomach cancer and migraine headaches. The human requirement for salt is only 220 mg/day, which is surpassed in most single servings of ready-to-eat cereals. If a random sample of 25 similar servings of Special K has a mean of sodium content of 244 mg of sodium and a standard deviation of 24.5 mg, does this suggest at the 0.01 level of significance that the average sodium content of single serving of Special K is greater than 220 mg? Assume the distribution of sodium contents to be normal.
