In the situation of Exercise 42, assume that the decision loss is "0-20" loss, that each observation costs c = 0.001, and that the prior probability that
 equals
   Find the Bayes sequential procedure. (You may use the small c approximations to the stopping boundaries, given in (7.84).)

In the situation of Exercise 4, show that a minimax sequential procedure is to choose the integer n which minimizes
  take a sample of size n, and estimate
