If this is greater than the first part of the number called by the spectator (i.e., ignoring the last two digits), then the last digit of your answer is the lower of the two possible values. Otherwise the last digit is the higher value. For example if the number called is 2809, the square root could be either 53 or 57.

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.
