Emilio got a score of 311.9; this version has a mean of 259 and a standard deviation of 23.

    Vincent and Reyna.

    Step-by-step explanation:

    To compare the performance of three potential employees, we have to convert each score into z score.

    Vincent got 83.5 for a N (68.2, 99)

    Z score for Vincent =

    Kaitlyn got 251.2 with N (238, 22)

    Z score for Kaitlyn =

    Reyna got a score of 8.04 for N (7.27, 0.7)

    Z score for Reyna =

    Z score higher is a better option since all z scores are positive

    Hence here Reyna is a good option.
