Preliminary data analyses indicate that you can consider the assumptions for using nonpooled t-procedures satised. Researchers obtained the data shown in the table on the number of acute postoperative days In the hospital using the dynamic and static systems. At the 10% signicance level. do the data provide sufcient evidence to conclude that the mean n_umber of acute postoperative days in the hospital is smaller with the dynamic system than with the static system? (Note: x.l = 7.50,s1=1.00.x2 =11.33, and s2 =4.18) a Click on the icon to yiew the data table. What are the hypotheses for the nonpooled Heel? 0 A He: :11 5 P2 Ha: "'1 > P2 0 C. Ho: [11: u: HI: "1
