iidLet X; > 0 be the total cost for subject i = 1, 2, ..., n. We model the data as X1, X2, ... , XnGam(a, B). Here, Gam(a, B) indicates the Gamma distribution with shape a > 0 and rate B > 0.BaThe corresponding density is f(x) = Hora-le-Ba for x > 0 and f(x) = 0 elsewhere. You must%3Duse this parameterization for the problem. Suppose that a is known, but 3 is unknown.Find the posterior density of B, fg|x (B | xn), under prior 3 ~ Gam(a, b), whereа.a > 0 and b > 0 are specified constants.b.Find the posterior mean of ß.
