Question

Three potential employees took an aptitude test. Each person took a different version of the test. The scores are reported below. Kaitlyn got a score of 79.7 ; this version has a mean of 73.7 and a standard deviation of 12 . Pierce got a score of 237.2 ; this version has a mean of 227 and a standard deviation of 17 . Norma got a score of 8.7 ; this version has a mean of 6.7 and a standard deviation of 0.8 . 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?

Answer 1

We see that Norma's z-score is highest hence company should offer the job to Norma.

Please comment if any doubt. Thank you.
