Refer to the Applied Psychology in Criminal Justice (Sept. 2009) investigation of the personality characteristics of drug dealers, Exercise. Convicted drug dealers were scored on the Wanting Recognition (WR) Scale—a scale which provides a quantitative measure of a person’s level of need for approval and sensitivity to social situations. (Higher scores indicate a greater need for approval.) Based on the study results, we can assume that the WR scores for the population of convicted drug dealers has a mean of 40 and a standard deviation of 5. Suppose that in a sample of n = 100 people, the mean WR scale score is x-bar = 42. Is this sample likely to have been selected from the population of convicted drug dealers? Explain.
