Critical Thinking Look at the histogram in Figure 2-10(a), which shows
mileage, in miles per gallon (mpg), for a random selection of older passenger
cars (Reference: Consumer Reports).
(a) Is the shape of the histogram essentially bimodal?
(b) Jose looked at the raw data and discovered that the 54 data values
included both the city and the highway mileages for 27 cars. He used the
city mileages for the 27 cars to make the histogram in Figure 2-10(b).
Using this information and Figure 2-10, parts (a) and (b), construct a his-
togram for the highway mileages of the same cars. Use class boundaries
16.5, 20.5, 24.5, 28.5, 32.5, 36.5, and 40.5.
