Quizplus · Accepted Answer

The exponential distribution can be used to model the time between events in a Poisson process, such as the arrival of cars at a tollbooth. Therefore, it is the most appropriate choice for describing the length of time it takes for the tollbooth attendant to service each driver. The normal distribution and uniform distribution are not appropriate because they do not capture the randomness and variability of service times. The Poisson distribution is not appropriate because it models the number of events in a fixed interval of time, rather than the time between events.
