DY0-001 · Question #93
Which of the following distribution methods or models can most effectively represent the actual arrival times of a bus that runs on an hourly schedule?
The correct answer is C. Normal. Scheduled buses tend to arrive around a fixed time with random delays that cluster symmetrically around the hour. A normal distribution effectively models those continuous, bell-shaped deviations from the exact schedule.
