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 the claim and thinks the manufacturer may be overstating the average gas mileage. Ifµ 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?
