Buyers are skeptical of an ATV advertisement that claims the newest model 4-wheeler gets an average of 17 miles per gallon. They believe the dealer is understating the average. Which null and alternative hypotheses should the buyer's test? Let µ represent the true average gas mileage. Group of answer choices H0: µ > 17 miles per gallon, Ha: µ ≥ 17 miles per gallon H0: µ ≤ 17 miles per gallon, Ha: µ < 17 miles per gallon H0: µ = 17 miles per gallon, Ha: µ > 17 miles per gallon H0: µ = 17 miles per gallon, Ha: µ < 17 miles per gallon H0: µ = 17 miles per gallon, Ha: µ ≠ 17 miles per gallon
