14-(5 pts) You are conducting a study on the effect of a new revolutionary ABC method aimed at increasing memory performance in humans. In order to verify the effectiveness of this method, you randomly selected 6 subjects drawn from a normally distributed population. First, you measured the memory performance of the subjects on a usual task of encoding nonsense words during a period of 30 minutes. You have entered the subjects' performance in the pre-test column. Subsequently, you taught the subjects the new ABC memory method. Finally, in order to verify the effectiveness of the ABC method, you remeasured the subjects' performance on the same type of encoding task. The subjects' performance was then encoded in the post-test column.
