An automobile manufacturer claims that the average gas mileage of a new model is 35 miles per gallon (mpg). A consumer group is skeptical of this claim and thinks the manufacturer may be understating the average gas mileage. If mean represents the true average gas mileage for this new model, which of the following gives the null and alternative hypotheses that the consumer group should test? Ha: mean = 35 miles per gallon (mpg) Ho: mean <35 miles per gallon (mpg) Ha: mean = 35 miles per gallon (mpg) Ho: mean >35 miles per gallon (mpg) Ha: mean = 35 miles per gallon (mpg) %3D Ho: mean #35 miles per gallon (mpg)
