    Answer:

    P (X > 52) = 0.5

    Step-by-step explanation:

    Standard Deviation = SD,

    Mean = M

    Since the Mean is 52 and the Standard Deviation is 8 we have:

    P (X<52) = P (X – M < 52 – 52) = P (X – M/SD < 52 – 52/8)

    Since X – M / SD = Z and 52 – 52/8 = 0 we have:

    P (X < 52) = P (Z < 0)

    Use the Standard Normal Distribution Table to find that:

    P (X < 0) = 0.5
