Let X1,.., Xn be i.i.d. Normal(theta,sigma^2).

(a) Suppose that theta is a priori distributed normal with mean mu and variance r^2. Determine the Bayes estimator of theta based from squared loss function. Compare its mean squared errpor MSE with the maximum likelihood estimator mle of theta.

(b) Assume now that has a double exponential distribution, that is, p(theta)= 1/(2a) * exp (-|theta|/a), a is known. Find the mean of the posterior distribution of theta.
