Question 3 2/2 pts An experiment is conducted to show that blood pressure can be consciously reduced in people trained in a biofeedback exercise program. Six (6) subjects were randomly selected and the blood pressure measurements were recorded before and after the training. The difference between blood pressures was calculated (after-before). The mean of the differences is -10.2 and the standard deviation of the differences is 8.4. = If a .05, the p-value and the conclusion are 0.0014; there is evidence that the blood pressure decreased after the training 0.0014; there is evidence that the blood pressure increased after the training 0.0155; there is evidence that the blood pressure decreased after the training 0.0155; there is evidence that the blood pressure increased after the training 0.3100; there is evidence that the blood pressure decreased after training
