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

Sagot :

Answer:

Norma should be offered the job.

Step-by-step explanation:

For Norma;

Population mean; μ = 67.5

Sample mean; x¯ = 84.5

standard deviation; σ = 10

Formula for the test statistic is;

z = (x¯ - μ)/σ

z = (84.5 - 67.5)/10

z = 1.7

For Rebecca;

Population mean; μ = 293

Sample mean; x¯ = 306.5

standard deviation; σ = 27

Formula for the test statistic is;

z = (x¯ - μ)/σ

z = (306.5 - 293)/27

z = 0.5

For Morgan;

Population mean; μ = 7.1

Sample mean; x¯ = 8.38

standard deviation; σ = 0.8

Formula for the test statistic is;

z = (x¯ - μ)/σ

z = (8.38 - 7.1)/0.8

z = 1.6

The person with highest z-score is Norma and as such he should get the job.
