*word problem* 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? a. the new drug does not appear to reduce the number of migraines since the rerandomized mean differences are considerably greater than the mean difference found between the two groups studied. b. the new drug appears to reduce the number of migraines since the rerandomized mean differences are considerably less than the mean difference found between the two groups studied. c. the new drug appears to reduce the number of migraines since the rerandomized mean differences are close to the mean difference found between the two groups studied. d. the new drug does not appear to reduce the number of migraines since the rerandomized mean differences are close to the mean difference found between the two groups studied.

For a science project, a high school research team conducted a survey of local air temperatures. based on the results of the survey, the found that the average temperatures were around 10 degrees higher than expected. this result was wrong. the trouble with the survey was that most of the locations were exposed to direct sunlight and located over asphalt or sand, which resulted in higher temperatures than normal. this is a classic example of an error in which phase of inferential statistics?
