At a computer disk drive factory, inspectors randomly pick a product from production lines to detect a failure. if the production lines are normal, this failure rate q0 = 10−4 . however occasionally some problems occur in the lines, in which case the rate goes up to q1 = 10−1 . let hi denote the hypothesis that the failure rate is qi . every morning, an inspector chooses drives at random from the previous day's production and tests them. if a failure occurs too soon, the company stops production and checks the critical part of the proc
