A nursing student is studying how long it takes patients to receive pain relief from minor to moderate headache from two different pain relievers. Subjects are randomly and independently assigned to two groups where one is giving the leading product and the other given a new drug about to be released. Subjects then record the time it takes to realize relief from pain. Is there evidence to suggest the new drug works faster than the old?
