To apply a Poisson probability distribution, the mean can be computed as __________. A) nπ C) e^-x

Question

Quizplus · Accepted Answer

The mean of a Poisson distribution is equal to the product of the rate parameter (λ) and the time or space interval of interest (t), which gives the expected number of events during that interval. The rate parameter is also equal to the product of the average rate of occurrence (μ) and the duration or area of interest (d). Therefore, the mean can be computed as either λt or μd. In the case of a Poisson distribution, the variance is also equal to λt or μd.
