If p = 2.4 % and n = 400, is the Poisson distribution a reasonable approximation of the binomial distribution? O yes no What is the mean of this binomial distribution (and the mean of the Poisson distribution used to approximate it)? mean = What is the standard deviation if the binomial distribution was used? Round to 2 decimals. standard deviation (actual) : What is the (approximate) standard deviation if the Poisson distribution was used?
