Anew drug claims to reduce insomnia. 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 3.3 nights they suffered insomnia a month. the group given the placebo reported an average of 9.5 nights they suffered insomnia a month. the data from the study are rerandomized 10 times. the difference of the means from rerandomization are 4.5, 4.0, 2.8, 4.3, 5.1, 1.9, 3.5, 4.7, 2.1, and 3.9. what is the most appropriate conclusion about the new drug to draw from this information? the new drug appears to reduce insomnia since the rerandomized mean differences are close to the mean difference found between the two groups studied. the new drug does not appear to reduce insomnia since the rerandomized mean differences are close to the mean difference found between the two groups studied. the new drug does not appear to reduce insomnia since the rerandomized mean differences are considerably greater than the mean difference found between the two groups studied. the new drug appears to reduce insomnia since the rerandomized mean differences are considerably less than the mean difference found between the two groups studied.
