Question: The number of errors x on page i is given for the first 6 pages of a textbook: 3 4 2 1 2 3 These numbers come from a Poisson distribution with unknown parameter 2, and they are independent when conditioned on 2. Recall that a Poisson distribution is given by: P(x[X) = x! Assume a prior for 2 such that: ma ml ~ xy, i.e. f (2) cc av/2-le 2 a) Describe the posterior of A, f (X(X1, ..., X6), given all the errors in the first 6 pages
