A fast-food company is developing a computer simulation involving arrival time at a drive-through restaurant. The distribution for arrival times is: Time Single-Digit Random Between Arrivals Probability Number Assigned 1 minute 0.1 0 2 minutes 0.2 1, 2 3 minutes 0.3 3, 4, 5 4 minutes 0.4 6, 7, 8, 9 Six random numbers are selected to represent the arrival of six cars: 1, 6, 9, 0, 5, 6. The mean time between arrivals for these cars, in this run of the simulation model, is:
