Do campers with trailers really get
better mileage per gallon on the
highway?
The table shows results from a study
of the MPG (miles per gallon) of
campers with trailers both in the
mountains and on desert roads. Assume that the two samples are randomly selected, independent, the
population standard deviations are not know and not considered equal. At the 0.05 significance level, test
the claim that the mpg on desert roads is better than in the mountains.
