A criminologist is searching through FBI files to document the prevalence of a rare double-whorl fingerprint. Among six consecutive sets of 100,000 prints scanned by a computer, the numbers of persons having the abnormality are 3, 0, 3, 4, 2, and 1, respectively. Assume that double whorls are Poisson events. Use the method of moments to estimate their occurrence rate, λ. How would your answer change if λ were estimated using the method of maximum likelihood?
i'm having trouble understanding method of moments problems, can someone please solve this so i can backtrack the solution and figure out how to do method of moments problems
(Poisson distribution) $$e^{-\lambda}\frac{\lambda^k}{k!}$$
