    A random variable X is normally distributed with µ = 60. Convert the value of X to a Z score, if the standard deviation is as given.
    X = 68 sd = 8

    and if the standard deviation is as follows:
    X = 72 sd = 3

    and if the standard deviation is as follows:
    X = 66 sd = 4

    Question #2 (three part question)
    a)Find the area under the standard normal curve between z = 0 and z = 3.

    b)Find the area under the standard normal curve to the right of z = 1.

    c)Find the area under the standard normal curve to the left of z = 1.5
