At a large university, 20% of students are enrolled in the nursing program. The dean of students selects a random sample of 20 students and records n = the number of students enrolled in the nursing program. The dean decides to simulate this random process by using a random number table. He assigns the digits to the outcomes.

1, 2 = student enrolled in nursing program

3-9, 0 = student not enrolled in nursing program

Here is a portion of a random number table.



In one trial of this simulation, 3 of the 20 randomly selected students are enrolled in the nursing program. Use line 2 to complete a second trial and then use line 3 to complete a third trial. Based on the results of these 3 simulations, what is the average number of students expected to be enrolled in the nursing program in random samples of size 20?
