The first group consisted of 9 people with the illness, and the second group consisted of 14 people with the illness. The first groupreceived treatment 1 and had a mean time until remission of 184 days, with a standard deviation of 7 days. The second group received treatment 2 and had amean time until remission of 172 days, with a standard deviation of 9 days. Assume that the populations of times until remission for each of the two treatmentsare normally distributed with equal variance. Can we conclude, at the 0.01 level of significance, that the mean number of days before remission after treatment1, u,, differs from the mean number of days before remission after treatment 2, u?Perform a two-tailed test.
