Question: At Small town U., there is one specialized graphics workstation for student use located across campus from the computer center. At 2:00 A.M. one day, six students arrive at the workstation to complete an assignment. A student uses the workstation for 10 ± 8 minutes, then leaves to go to the computer center to pick up graphics output. There is a 25% chance that the run will be OK and the student will go to sleep. If it is not OK, the student returns to the workstation and waits until it becomes free. The round trip from workstation to computer center and back takes 30 ± 5 minutes.

The computer becomes inaccessible at 5:00A.M. Estimate the probability, p ,that at least five of the six students will finish their: assignment in the 3-hour period. First, maker = 10 replications, and compute a 95% confidence interval for p. Next, work out the number of replications needed to estimate p within ±.02, and make this number of replications. Recompute the 95% confidence interval for p.
