TABLE 9-2
An appliance manufacturer claims to have developed a compact microwave oven that consumes a population mean of no more than 250 W.

If there is evidence that the population mean consumption is greater than 250 W, the manufacturer will be unable to make the claim.
-Referring to Table 9-2, if you select a sample of 20 compact microwave ovens and are willing to have a level of significance of 0.01, the power of the test is ________ if the mean power consumption of all such microwave ovens is in fact 248 W.
