study of memory

  

In a study of memory recall, 5 people were given 10 minutes to memorize a list of 20 words. Each was asked to list as many of the words as he or she could remember both 1 hour and 24 hours later. The result is shown in the following table.

Subject, 1 hour words, 24 hour words

1, 13, 13

2, 18, 16

3, 10, 9

4, 15, 14

5, 11, 11

identify the null hypothesis and the alternative, determine the test statistics and determine the p- value and determine if the evidence support the claim that the mean number of words recalled after 1 hour exceeds the mean recall after 24 hours
