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)
producing the following results:
xd = ? 10.2, sd = 8.4.
using the data, test the hypothesis that the blood pressure has decreased after the training.
what is the distribution for the test?
