Write three equivalent fractions for 3/5 showing how you received your answer

Tobias should be offered the job.

Step-by-step explanation:

Z-score:

In a set with mean and standard deviation , the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question:

The applicant with the highest z-score should be chosen.

Tobias:

Score of 84.5, in a version with mean 66.9 and standard deviation 11. His z-score is found when

Kiersten:

Score of 281.8, in a version with mean 261 and standard deviation 26. His z-score is found when .

Pierce:

Score of 7.69, version with mean 7.2 and standard deviation 0.7. His z-score is found when .

Due to the higher z-score, Tobias should be offered the job.
