The health center of a small university requires students to have appointments for visits. Appointments take an average (mean) of 6.1 minutes with a standard deviation of 3.9 minutes. The health center makes 100 appointments each day and is scheduled to be open for 10 hours. What is the probability that the total time spent for 100 students who have appointments for tomorrow will not exceed 10 hours? (Hint: 10 hours=600 minutes.)
