(a) Using software, tabulate the frequencies of the makes of cars.
(b) What is the mode of the make of car?
(c) Generate a pie chart that shows all of the relative frequencies. What’s a problem with this chart?
(d) Recode the variable that identifies the make of the car so that the resulting pie chart distinguishes the shares of the top five makes. Draw the new pie chart.
