Question

Read the following scenario and complete each of the seven problems below: A drug company wants to compare the effect of three different medicines (Drug A, Drug B, and Drug C) on reducing the pain associated with migraine headaches. They asked 39 migraine sufferers to take the medicine at the beginning of their next migraine attack and to record their highest pain level during the migraine based on a scale of 1 (slight pain) to 10 (severe pain). The results of the study are in the table below.
