Repeat Exercise 40, assuming that the observations are N(0, o2), o2 unknown (instead of o = 1), and that g(0) is (4.01, 0.34) and o

Repeat Exercise 40, assuming that the observations are N(0, o2), o2 unknown

(instead of o² = 1), and that g(0) is €(4.01, 0.34) and o² has (independently)the noninformative prior **(2) = 02:

(a) Use the (4.150) approximation.

(b) Use the approximation to m(xg1, **) in Exercise 144.
