[9] A study was conducted to investigate the effect of physical training on serum motlevel. Eleven subjects participated in the study. Prior to training, blood samples were taken to determine Wlevels of each subject. Then the subjects were put into training program. At the end of the program, blood samples were taken again and Wlevels on each subject were recorded. Paired t-test was performed on the resulting data. The following is summary information: Mean of the difference = D = 33.182 Variance of the difference = SZD = 2607.7364 At the 5% level of signicance, is there any difference between mean Wlevel before and after the training program? {Follow the Hypothesis testing procedure to arrive at a conclusion] Test Statistics to use: T = D SD/Vn (15 Points)
