In a study of memory recall, 8 students from a large psychology class were selected at random and given 10 min to memorize a list of 20 nonsense words. Each was asked to list as many of the words as he or she could remember both 1 hour and 24 hours later, as shown in the following table:

Subject 1 2 3 4 5 6 7 8

1 Hour 14 12 18 7 11 9 16 15

24 Hours 10 4 14 6 9 6 12 12

Is there evidence to suggest that the mean number of words recalled after 1 hour exceeds the mean recall after 24 hours by more than 3? Use a level .01 test.
