Note:
The answers vary a bit. This is due to rounding in the workbooks.
Example 10-2:
It is estimated that approximately 53 percent of college
students graduate in 5 years or less. This figure is affected by the fact that
more students are attending college on a part-time basis. If 500 students on
a large campus are selected at random, what is the probability that between
50 and 60 percent of them will graduate in 5 years or less?
