40. In Example 7.30, we started with U I(X1 0) and used a conditional expectation argument to obtain an unbiased estimator of the zero-defect probability based on the suf cient statistic. Consider starting with a different statistic: .

Show that the improved estimator based on the suf cient statistic is identical to the one obtained in the cited example. [Hint: Use the general property
