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 breakouts a month. The group given the placebo reported an average of 4.5 breakouts a month. The data from the study are rerandomized 10 times. The difference of the means from rerandomization are 1.5, 3.0, 1.8, 1.3, 2.1, 1.9, 2.5, 0.7, 2.1, and 1.9. What is the most appropriate conclusion about the new drug to draw from this information? \\ The new drug does not appear to reduce the number of eczema breakouts since the rerandomized mean differences are close to the mean difference found between the two groups studied. _ The new drug appears to reduce the number of eczema breakouts since the rerandomized mean differences are close to the mean difference found between the two groups studied. The new drug appears to reduce the number of eczema breakouts since the rerandomized mean differences are considerably less than the mean difference found between the two groups studied. a The new drug does not appear to reduce the number of eczema breakouts since the rerandomized mean differences are considerably greater than the mean difference found between the two groups studied. A randomized study compared two drugs that are designed to increase a child's human growth hormone level. It was found that over a 1-year period, those receiving Drug A increased their hormone level by a mean of 28 IU. Those receiving Drug B increased their hormone level by a mean of 15 IU (IU = International unit). To determine whether the results are significant, the data are rerandomized and the difference of the means is shown in the dot plot. What is the best conclusion to make based on the data? The difference of the means is not significant because ' the rerandomizations show that it is within the range of what likely happens by chance. The difference of the means is significant because the rerandomizations show that it is outside the range of what likely happens by chance. The difference of the means is not significant because 0 the rerandomizations show that it is outside the range of what likely happens by chance. The difference of the means is significant because the rerandomizations show that it is within the range of what likely happens by chance.
