3. A fuel company wished to compare the fuel efciency of two different gasoline blends, A and B. To do so, they randomly selected ve cars. Each car was driven twice, once using blend A and once using blend B. The fuel consumption results and summary statistics (in litres per 100 km) for each car were as follows mun-I m Is there evidence to suggest that the average fuel consumption gasoline for blend A is greater than that of gasoline blend B? Perform an appropriate hypothesis test using the critical value method at a 5% signicance level. You may assume that the difference in fuel consumption (Blend A Blend B) for the population of all cars is normally distributed
