Step 1-5: step 1: state the null and aternative hypothesis for the teststep 2: find the value of the standard deviationof the paired differences. Round your answer to one decimal placestep 3: compute the value of the test statistic. Round your answer to three decimalmplacesstep 4: find the p-value for the hypothesis test, Round your answer to four decimal places.step 5: draw a conclusion for the hypothesis test (reject/fail to reject, there isot sufficient evidence

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 = (number of sit-ups that can be done after taking the course)-(number of sit-ups that can be done prior to taking the course) . Use a significance level of a = 0.01 for the test. Assume that the numbers of sit-ups are normally distributed for the population both before and after taking the fitness course.
