    Answer:

    Z score is a statistical that corresponds to the standarization of the regular score to a normal dsitribution

    The formula for Z score is Z = [X – mean ]./ (standar deviation)

    Here X = 930.00; mean = 900.00; and standard deviation = 15.00

    Then, Z = [930.00 – 900.00] / 15.00 = 30.00 / 15.00 = 2.00

    Answer: 2.00
