The cold medicine Dozenol lists 600 mg of acetaminophen per fluid ounce as an active ingredient. The Food and Drug Administration would like to make sure that Dozenol contains the correct amount. Assume that the amount of acetaminophen per fluid ounce is normally distributed with standard deviation 21 mg. They test 65 one-ounce samples of the medicine and finds that the mean amount of acetaminophen for the sample is 589 mg. Does this give them sufficient evidence that Dozenol contains the correct amount of acetaminophen?
