question 24

Short Answer

TABLE 9-1

The operations manager stops the production process if there is evidence that the population mean light bulb life is below 500 hours.
-Referring to Table 9-1, if you select a sample of 100 light bulbs and are willing to have a level of significance of 0.01, the probability of the operations manager not stopping the process if the population mean bulb life is 510 hours is ________.
