Suppose that a bookbag were filled with 100 poker chips. You know that either 70 of the chips are red and the remainder blue, or that 70 are blue and the remainder red. Ten chips are to be drawn successively with replace¬

ment. You must decide whether the composition of the bookbag is 70R — 30B or 70B — 30R. Find a decision rule that will make the probabilities of the possible errors in inference small and equal. [Hint: Use the binomial distri¬

bution with N = 10, first with p — .70 and then with p = .30.]
