WebSince the mean value of is and the variance is , the distribution should be approximately . Figure 7.2.8. Gaussian approximation to the binomial. Use of the generating function shows that the sum of independent Poisson random variables is Poisson. Now if ), then may be considered the sum of independent random variables, each Poisson ( ). WebThe time is known to have an exponential distribution with the average amount of time equal to four minutes. X is a continuous random variable since time is measured. It is given that μ = 4 minutes. To do any calculations, you must know m, the decay parameter. m = 1 μ. Therefore, m = 1 4 = 0.25.
