Suppose that x has a Poisson distribution with μ = 5. (a) Compute the mean, μx,...

Suppose that x has a Poisson distribution with μ = 5. (a) Compute the mean, μx, variance, σ2x , and standard deviation, σx. (Do not round your intermediate calculation. Round your final answer to 3 decimal places.) µx = , σx2 = , σx = (b) Calculate the intervals [μx ± 2σx] and [μx ± 3σx ]. Find the probability that x will be inside each of these intervals. Hint: When calculating probability, round up the lower interval to next whole number and round down the upper interval to the previous whole number.
