A new hybrid car uses 3.8 litres of gasoline per 100 kilometres for city driving, according to websites advertising the car. Of course, not all of these cars are going to get the same fuel economy in all cities with all drivers. Would you expect the interquartile range (IQR) to be approximately 0.01, 1.0, or 5.0 L/100 km? Give a reason for your answer. Given your estimate of the IQR, what is your estimate of a range of reasonable values for the variance? Be sure to state the units of measurement, and give a reason for your answer.
