For questions, refer to the following information:Researchers conducted a study to investigate some effects of physical training. The sample data provided below represent forced expiratory volume (FEV) before (pre) and after (post) training. The sample mean of the differences between the posttraining and pretraining weights is .32. The sample standard deviation is .40. Using a 0.05 significance level, you need to test the claim that training raises the FEV within subjects post training, i.e. that the mean value of the differences (post - pre) is greater than 0. To do so, answer each of the followingquestions.
