In Example 46, for estimating n = 0, (a) verify (4.134); (b) show that, on any bounded set of x, there exists an admissible estimator

In Example 46, for estimating n = 0²,

(a) verify (4.134);

(b) show that, on any bounded set of x, there exists an admissible estimator which is arbitrarily close to 8"(x) = x²+p.
