A drug used for treating cancer has potentially dangerous side effects if it is taken in doses higher than needed for treatment. The pharmaceutical company that manufactures the drug must be certain that the standard deviation of the drug content in each tablet is less than 0.1 mg. Fifteen tablets are analyzed to determine the amount of the drug in them. The sample mean is 20 mg, and the sample standard deviation is 0.08 mg.
