The null hypothesis would be that the mean is equal to or less than 32 miles per gallon. If the conclusion is to reject the null hypothesis, it means that there is sufficient evidence to support the alternative hypothesis that the mean is greater than 32 miles per gallon, which aligns with Carter Motor Company's claim that the Libra will average better than 32 miles per gallon in the city. Therefore, choice D is the correct answer.
