Aconsumer group plans to test whether a new passenger car that is advertised to have a mean highway miles per gallon of at least 33 actually meets this level. they plan to test the hypothesis using a significance level of 0.05 and a sample size of nequals100 cars. it is believed that the population standard deviation is 3 mpg. based upon this information, if the "true" population mean is 32.0 mpg, what is the probability that the test will lead the consumer group to "accept" the claimed mileage for this car? round to four decimal places.
