A study of college freshman revealed that 29% had no work experience prior to entering college. Suppose a group of 75 college freshmen is chosen at random.

1. What is the probability that less than 18 of the students selected had no work experience prior to entering school? (Write probability statement and calculator command that you utilized in determining the probability!)
2. List the three reasons why the normal distribution can be used to determine the probability of this sample proportion.
