In Problem 6 you found a confidence interval for the difference from previously gathered data. In this problem you want to set the sample size for the two groups before conducting the study This will often be the case for clinical data where you want to make sure that, if a particular difference in two groups of the amount or level of a substance exists, your test will come back saying that such a difference exists. In other words, you...
