There must be sufficient information SOMEWHERE or SOMEHOW. Post the exact wording of a problem statement. Let's see what comes up.

consumer 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 .05 and a sample size of n=100 cars. It is believed that the population standard deviation is 3 mpg. Based upon theis information, if the 'Ture" population mean is 32 mpg, what is the probability that the test will lead the consumer group to reject the claimed mileage for this car?
A about .075
B .05
C approximately .95
D none of the Above.


Hopefully you can help me figure this out!
