Quizplus · Accepted Answer

The exponential distribution is appropriate for measuring the length of time between arrivals at a grocery checkout counter because it models the waiting time for an event to occur in a Poisson process, where events occur randomly and independently over time. In this case, customers arrive randomly and independently at the checkout counter, making the exponential distribution an appropriate choice for measuring the time between arrivals.
