CompTIA DataX (DY0-001) — Question 17

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?

Answer options

• A. Binomial
• B. Exponential
• C. Normal
• D. Poisson

Correct answer: C

Explanation

The Normal distribution is appropriate for representing the actual arrival times of a bus due to the nature of continuous time and expected variability around a mean arrival time. The Binomial and Poisson distributions are more suited for discrete events, while the Exponential distribution is typically used for time until an event occurs, rather than scheduled arrivals.
