question 56

Short Answer

SCENARIO 9-14
An appliance manufacturer claims to have developed a compact microwave oven that consumes a population mean of no more than 250 W.From previous studies,it is believed that power consumption for microwave ovens is normally distributed with a population standard deviation of 15
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 Scenario 9-14,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.
