Researchers wish to determine if a new experimental medication will reduce the symptoms of allergy sufferers without the side effect of drowsiness. To investigate this question, the researchers give the new medication to fifty adult volunteers who suffer from allergies. Forty-four of these volunteers report a significant reduction in their allergy symptoms without any drowsiness. Twenty sets of identical twins were used to investigate this question. One member of each set of twins used the mouthwash after each brushing, the other did not.
