Historically, the proportion of people who trade in their old car to a car dealer when purchasing a new car is 48%. Over the previous 6 months, in a sample of 115 new-car buyers, 46 have traded in their old car. To determine whether the proportion of new-car buyers that trade in their old car has statistically significantly decreased, what is the null and alternative hypothesis?
