Question

To test the effect of a physical fitness course on one's physical ability, the number of sit-ups that a person could do in one minute, both before and after the course, was recorded. Ten individuals are randomly selected to participate in the course. The results are displayed in the following table. Using this data, find the 95 % confidence interval for the true difference in the number of sit-ups each person can do before and after the course. Assume that the numbers of sit-ups are normally distributed for the population both before and after completing the course. Show supporting work for each step that follows. Sit-ups before: 30, 36, 22, 56, 28, 23, 33, 33, 29, 28 Sit-ups after: 42, 43, 30, 58, 44, 32, 44, 47, 47, 43 Step 4 of 4: Construct the 95 % confidence interval. Round your answers to one decimal place. Lower endpoint: Upper endpoint:
