The cost of manufacturing vehicles in Mexico is very attractive to automakers. Global carmakers build approximately 1.9 million vehicles in Mexico. Of these, nearly 76% are exported, primarily to the US. Although General Motors is the largest manufacturer in Mexico, Daimler Chrysler exports the most vehicles. Automotive analysts examine both the number of vehicles produced and the number exported (see the data file "Automotive") to determine the potential market share of each company.
a) For the data on vehicles produced in Mexico, construct a bar chart displaying the amount produced by each company.
b) Repeat part a) using a pie-chart.
c) Construct a bar chart displaying the number of vehicles exported from Mexico.
d) Repeat part d) using a pie-chart.
e) Do you prefer the bar charts or the pie charts for displaying the data? Explain.
f) What differences do the charts reveal for the automotive companies with respect to the number of vehicles produced and number of vehicles exported?
