1. The Poisson distribution is often used to describe how many times an event takes place within a certain time interval, such as number of daily customers at a store. Assume x1,..., xn ~iid Poisson(A), where X is the rate of occurrences. Calculate the maximum likelihood estimator of A with pen and paper or LaTeX, showing your work. The probability mass function (PMF) for the Poisson distribution is: f(x|A) = x!
