Binomial and poisson distribution examples
WebApr 2, 2024 · When the Poisson is used to approximate the binomial, we use the binomial mean μ = n p. The variance of X is σ 2 = μ and the standard deviation is σ = μ. The Poisson approximation to a binomial distribution was commonly used in the days before technology made both values very easy to calculate. Example 4.7. 7. WebJun 1, 2024 · a) A binomial random variable is “BI-nary” — 0 or 1. In the above example, we have 17 ppl/wk who clapped. This means 17/7 = 2.4 people clapped per day, and 17/ (7*24) = 0.1 people clapping per hour. If …
