Morgan got a score of 288.6; this version has a mean of 279 and a standard deviation of 16.

Reyna got a score of 7.92; this version has a mean of 7.4 and a standard deviation of 0.4.

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:

Thomas

Morgan

Reyna

Explanation / Answer

PROBABILITY OF GETTING A JOB OF THOMAS IS HIGHER ,AS

IN FIRST CASE OF THOMAS, MEAN =66.3 AND STD =12

SO Z VALUE IS 1.7

SO , FROM TABLE WE CAN CONCLUDE THE P (Z=1.7) i.e. 0.9554

But in case of morgan and Reyna , the z value is 0.6 and 1.3 respectively and hence the probability of getting selected is 0.7257 and 0.9032 respectuvely.
