Look at the histogram below, which shows mileage, in miles per gallon (mpg), for a random selection of passenger cars.†

(a) Is the shape of the histogram essentially bimodal?

Yes, because the histogram has one peak. Yes, because the histogram has two peaks. No, because the histogram has one peak. No, because the histogram has two peaks.

(b) Jose looked at the raw data and discovered that the 54 data values included both the city and highway mileages for 27 cars. He used the city mileages for the 27 cars to make the histogram below.

Using this information and the histograms shown above, construct a frequency table 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.
