An offshore orice flow meter is regulated so that the amount of oil dispensed averages 240 mL with a standard deviation of 15 ml... Periodically, the meter is checked by taking a sample of 40 cans and computing the average content. If the mean of the 40 cans is a value within the interval pi i 203?, the flow meter is thought to be operating satisfactorily; otherwise, a calibration is made. The company ofcial found the mean of 40 cans to be i = 236 mL and concluded that the flow meter needed no calibration. Was this a reasonable decision
