An experiment is conducted to show that blood pressure can be consciously reduced in people trained in a "biofeedback exercise program." Eight subjects were randomly selected and blood pressure measurements were recorded before and after the training. The difference between blood pressures was calculated (after - before) producing the following results: x= -10.2, s. = 8.4. Using the data, test the hypothesis that the blood pressure has decreased after the training. If a = 0.05, find the p-value. (Round your answer to four decimal places.) 0.0093 X What can we conclude? There is insufficient evidence to conclude that the blood pressure decreased after the training. There is sufficient evidence to conclude that the blood pressure increased after the training. There is sufficient evidence to conclude that the blood pressure decreased after the training. There is insufficient evidence to conclude that the blood pressure increased after the training
