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 99 % 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. Sit-ups before 42 22 21 44 30 47 39 46 34 33 Sit-ups after 60 33 32 52 34 51 48 57 45 41 Copy Data Step 1 of 4: Find the point estimate for the population mean of the paired differences. Let x¡ be the number of sit-ups before taking the course and x2 be the number of sit-ups after taking the course and use the formula d = x2 – x1 to calculate the paired differences. Round your answer to one decimal place.

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 99 % 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.

Step 1 of 4: Find the point estimate for the population mean of the paired differences. Let x¡ be the number of sit-ups before taking the course and x2 be the number
of sit-ups after taking the course and use the formula d
= x2 – x1 to calculate the paired differences. Round your answer to one decimal place.
