(a) (2 points) Find the kernel of the posterior distribution of X1=x1,,Xn=xn. Identify it as a distribution from Chapter 2 and specify the parameters. (b) (1 point) What is the prior belief about the value of that is encoded by this choice of prior? How does this impact the final posterior distribution?.
