Researchers interested in determining the relative effectivenes of two different drug treatments on people with a chronic illness established two independent test groups. The first group consisted of 15 people with the ilness, and the second group consisted of 11 people with the iness. The first group received treatment I and had a mean time until remission of 180 days with a standard deviation of 6 days. The second group recerved treatment 2 and had a mean time until remission of 163 days with a standard deviation of 9 days. Assume that the populations of times until remission for each of the two treatments are normally distributed with equal variance. Construct a 95% confidence interval for the difference , between the mean number of days before remission after treatment 1 () and the mean number of days before remission after treatment 2 (). Then complete the table below. Carry your wntermedate computations to at least three decimal places. Round your responses to at least two decimal places.
