A study of “adverse symptoms” in users of over-the-counter pain relief medications assigned subjects at random to
one of two common pain relievers: acetaminophen and ibuprofen. In all, 650 subjects took acetaminophen, and 44
experienced some adverse symptom. Of the 347 subjects who took ibuprofen, 49 had an adverse symptom. Is this
convincing evidence that the two pain relievers differ in the proportion of people who experience an adverse symptom?
