1. Recall that a normal distribution should be able to spread approximately three standard deviations from the mean value and that the mean and variance of a Poisson distribution are equal. What minimum value should n *λ take on to ensure that the sampling distribution for the sample mean from a Poisson(2) distribution will be approximately normal?
