A fitness course claims that it can improve an individual's physical ability. 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. Can it be concluded, from the data, that participation in the physical fitness course resulted in significant improvement?

Let d=(numberofsit-upsthatcanbedoneaftertakingthecourse)(numberofsit-upsthatcanbedonepriortotakingthecourse)

Use a significance level of =0.01. Assume that the numbers of sit-ups are normally distributed for the population both before and after taking the fitness course.

Sit-ups before 21, 44, 34, 22, 27, 22, 52, 36, 39, 31

Sit-ups after 35, 59, 43, 30, 31, 34, 54, 52, 48, 48

Find thep-value for the hypothesis test. Round your answer to four decimal places.
