Consider the Binomial random variable X - Binom(N,) for unknown sample size pa- rameter N. Show that T = 2X is an unbiased estimator for the parameter N. Now consider the independent random variables X1,..., Xm that all follow the afore- mentioned Binomial distribution. Using the above information, construct a consistent estimator for N.
