An experiment was designed to study whether eye pupil size is related to a person's attempt at deception. Eight students were asked to respond verbally to a series of questions. Before the questioning began, the size of one of each student's pupils was noted and the students were instructed to answer some of the questions dishonestly. (The number of questions answered dishonestly was left to individual choice.) During questioning, the percentage increase in pupil size was recorded.

Each student was then given a deception score based on the proportion of questions answered dishonestly. (High scores indicate a large number of deceptive responses.) The results are shown in the table (p. 14-56) and saved in the DECEPEYE file. Can you conclude that the percentage increase in eye pupil size is positively correlated with deception score? Use α = .05.
