    Based on past data it would be

    reasonable to assume that 6.68% of all

    the scores on the next text will be 15 or

    more. If we then run the test and 37% ofthe tests are above 15, we would need

    to investigate why.

    Note: Because we are dealing with

    continuous random variables and we are

    calculating probability from area and

    because the area of a line is zero, P(>=15) =

    P(>15)
