Therefore solution for a is
Answer:
Vincent and Reyna.
Step-by-step explanation:
As z-score indicates that a data point is how many standard deviation above mean, so to find which of three applicant should be offered the job, let us find the z-score for each person using z-score formula.
, where,
= z-score,
= Random sample score,
= Mean,
= Standard deviation.
Therefore, Vincent's score on aptitude test is 1.7 standard deviation above mean.
Therefore, Kaitlyn's score on aptitude test is 0.6 standard deviation above mean.
Therefore, Reyna's score on aptitude test is 1.2 standard deviation above mean.
Since Vincent and Reyna has higher z-scores, therefore, they are further above mean than Kaitlyn. Therefore, Vincent and Reyna should be offered the job.
