Three potential employees took an aptitude test. each person took a different version of the test. the scores are reported below

timama [110]

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.

$z=\frac{x-\mu}{\sigma}$ , where,

$z$ = z-score,

$x$ = Random sample score,

$\mu$ = Mean,

$\sigma$ = Standard deviation.

$\text{z-score for Vincent}=\frac{83.5-68.2}{9}$

$\text{z-score for Vincent}=\frac{15.3}{9}$

$\text{z-score for Vincent}=1.7$

Therefore, Vincent's score on aptitude test is 1.7 standard deviation above mean.

$\text{z-score for Kaitlyn}=\frac{251.2-238}{22}$

$\text{z-score for Kaitlyn}=\frac{13.2}{22}$

$\text{z-score for Kaitlyn}=0.6$

Therefore, Kaitlyn's score on aptitude test is 0.6 standard deviation above mean.

$\text{z-score for Reyna}=\frac{8.04-7.2}{0.7}$

$\text{z-score for Reyna}=\frac{0.84}{0.7}$

$\text{z-score for Reyna}=1.2$

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.
