Question

Three potential employees took an aptitude test. Each person took a different version of the test. The scores are reported below. Morgan got a score of 81.7; this version has a mean of 60.9 and a standard deviation of 13. Frankie got a score of 314.8; this version has a mean of 294 and a standard deviation of 26. Rebecca got a score of 7.5; this version has a mean of 7.2 and a standard deviation of 0.6. 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

Answer:

Morgan.

Step-by-step explanation:

The applicant who has the highest z-score would be the one who performs best.

z-score = (s - m)/ d       where  s = score, m = mean and d = the standard deviation.

Morgan's z-score = (81.7 - 60.9) / 13

= 1.6

Frankie's = (314.8 - 294) / 26

= 0.8.

Rebecca's = (7.5 - 7.2) / 0.6

= 0.5.
