Three potential employees took an aptitude test. Each person took a different version of the test. The scores are reported below. Alissa got a score of 68.5; this version has a mean of 60.4 and a standard deviation of 9. Morgan got a score of 252.5; this version has a mean of 227 and a standard deviation of 17. Norma got a score of 7.96; this version has a mean of 6.7 and a standard deviation of 0.7. If the company has only one position to fill and prefers to fill it with the applicant who performed best on the aptitude test, which of the applicants should be offered the job?
