A study is conducted in which a random sample of 24 adults are divided equally into two groups and given a list of 24 words to memorize. During a break, one group takes a 90 minute nap while another group is given a caffeine pill. The response variable of interest is the number of words participants are able to recall following the break. We are testing to see if there is a difference in the average number of words a person can recall depending on whether the person slept or ingested caffeine. The data ¹ are shown in Table 1 below. Sleep Caffeine 14 18 11 12 12 14 13 13 18 6 17 21 18 14 16 9 16 17 7 10 Table 1: Number of words recalled 14 15 15 10 Mean 15.25 Mean = 12.25
