Recovering from surgery: A new postsurgical treatment was compared with a standard treatment. Ten subjects received the new treatment, while ten others (the controls) received the standard treatment. The recovery times, in days, are given below. Treatment: 15 16 17 19 23 24 25 26 27 28 Control: 11 12 14 16 17 N9 20 21 22 23 Send data to Excel Can you conclude that the mean recovery time for those receiving the new treatment is greater than the mean for those receiving the standard treatment? Let Hi denote the mean recovery time for the new treatment. Use the a=0.10 level of significance and the TI-84 Plus calculator.
