(a) Let X1, X2, ..., Xn be a random sample from a Poisson distribution with mean λ. Use mathematical expressions in R Markdown to show what the maximum likelihood estimator λ̂ is. (b) What is the exact variance of λ̂? (c) Using Fisher Information find the asymptotic variance of λ̂. Is it the same as in (1.b.)?
