Question: In the past, many bodily functions were thought to be beyond conscious control. However, recent experimentation suggests that it may be possible for a person to control certain bodily functions if that person is trained in a program of biofeedback exercises. An experiment is conducted to show that blood pressure levels can be consciously reduced in people trained in this program. The blood pressure measurements (in millimeters of mercure0 listed in the table represent readings before and after the biofeedback training of sex subjects. Is there sufficient evidence to conclude that the mean blood pressure after people are trained in this program is less than the mean blood pressure before training? Using the relevant output below, conduct hypothesis test using = .05. use critical value approach to hypothesis testing. Show the different steps!
