In an experiment to gauge the efficacy of this treatment for knee injuries, seven subjects with recent knee injuries were enrolled in a trial. The range of motion (in degrees) of the joint was measured first. After a prescribed ultrasound treatment, the range of motion was measured again. Table 1 below contains the pre and post treatment responses from each of these subjects. Pre 30.5 Table 1: Knee extensions (degrees) before and after ultrasound Post 47.6 20.9 23.8 50.2 57.2 41.6 42.5 52.9 Diff 9.6 53.2 48.9 - 2.6 45.9 67.2 X 8.3 54.8 -4.3 - 1.9 A) In the table above, enter the differences (computed Pre - Post) in the empty cells. B) Based on the sample, the average difference in the pre and post treatment responses is -6.43 x . (2 decimal places) C) The margin of error for a 98% confidence interval for the true average difference in knee extension before versus after ultrasound treatment is 17.99. Using this margin of error , determine the lower and upper limits for the confidence interval.
