What would be your decision? A. There is insufficient data to make a decision. B. do not reject the null hypothesis. C. Reject the null hypothesis. D. Reject the alternative hypothesis.
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.
