    Answer:

    Z = 1.5

    Step-by-step explanation:

    The equation of to get the z-score is as follows:

    z = \frac{x - mean}{standard:deviation}

    X represents the value

    Now, let’s plug everything given into the equation:

    Value = 27

    Mean = 24

    Standard deviation = 2

    Z = \frac{27-24}{2}

    Solve

    Z = \frac{3}{2} \\Z = 1.5

    Therefore, the z-score is 1.5.

    I hope this helps!
