### 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 known 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.#### MPG on Desert Roads```31.4 29.6 29.2 29.830.8 27.5 30.7 25.828.4 34.8 35.7```#### MPG in the Mountains```26.3 26.2 24.8 26.325.3 24.4 23.3 26.024.5```### Hypotheses:What are the correct hypotheses?
