Question: A night time cold medicine bears a label indicating the presence of 600 mg of acetaminophen in each fluid ounce of the drug. Suppose that Health Canada randomly selected 65 one-ounce samples and found that the mean acetaminophen content was 589 mg and the standard deviation was 21 mg. Using α = 0.02, test the claim of the pharmaceutical company that the population mean is different from 600 mg. Would you by this cold medicine? Give your reasons.
