Question: Assume that X1, X2, is a sequential sample from a 4(1, 0) density, that it is desired to estimate & under decision loss L(0, a)=(-a)2/02,

Assume that X1, X2, is a sequential sample from a 4(1, 0) density, that it is desired to estimate & under decision loss L(0, a)=(-a)2/02, and that the cost of a fixed sample of size n is C(n) =nc. If 8 has an 99

(a, ) prior density, approximate the optimal fixed sample size.
