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.

The new drug appears to reduce insomnia since the rerandomized mean differences are close to the mean difference found between the two groups studied.

Step-by-step explanation:

The group given the new drug reported an average of 3.3 nights they suffered insomnia a month. Therefore the mean of this group is 3.3.

On the other hand, the control group receiving the placebo reported an average of 9.5 nights they suffered insomnia a month. Therefore, the mean of this control group is 9.5.

The population mean difference between these two groups is thus;

9.5 - 3.3 = 6.2

This difference is very significant inferring that the new drug appears to reduce insomnia. Nevertheless, this mean difference is considerably close to the difference of the means from re randomization. Therefore we can conclude that,

The new drug appears to reduce insomnia since the rerandomized mean differences are close to the mean difference found between the two groups studied.

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!
