Preliminary analyses indicate that you can consider the assumptions for using nonpooted t-prooedures satised' Researchers obtained the following data on the number of acute postoperative days in the hospital using the dynamic and static systems. Obtain a 90% condence interval for the difference, p1 - F2. between the mean numbers of acute postoperative days in the hospital with the dynamic and static systems. (Note: i1 = 7.50, 51 = 1.93, :22 =10.50, and 82 = 3.02) The 90% confidence interval is from D to E]. (Round to three decimal places as needed.)
