A new drug claims to reduce the number of migraines an individual suffers. In a study on the effectiveness of the new drug, 50 subjects were given the new drug and another 50 subjects were given a placebo. At the end of the 6-month study, the group given the new drug reported an average of 1.3 migraines a week. The group given the placebo reported an average of 2.5 migraines a week. The data from the study are rerandomized 10 times. The difference of the means from rerandomization are 1.2, 3.4, 1.8, 1.3, 1.1, 0.9, 2.5, 0.7, 1.1, and 0.9. What is the most appropriate conclusion about the new drug to draw from this information?
