11. 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 body 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 these techniques. Blood pressure measurements (in millimeters of mercury] are recorded for seven randomly selected subjects, who then participate in the training. After the training, new blood pressure measurements are recorded. The data are in le c09s03e05. A. Is there sufcient evidence to conclude that the training produces a reduction in mean blood pressure for participants? Use . B. When the experimenters learn that the study indicates a reduction in mean blood pressure for people trained in this program, they want to know how much the blood pressure is reduced. Estimate the mean reduction in blood pressure for people trained in this program. Use 95% condence
