Question

Quizplus · Accepted Answer

The interarrival times and service times of customers are commonly described by the exponential distribution, which models the time between events occurring at a constant rate. The Poisson distribution is used to model the number of events occurring in a fixed interval of time, while the Rayleigh and lognormal distributions are typically used to describe continuous variables with positive values, such as wind speeds or stock prices.
