Question

a. Use the information in the graphical display to construct a single segmented bar graph for the ethnicity data.
b. Do you think that the original graphical display or the one you created in Part (a) is more informative? Explain your choice.
c. Why do you think that the original graphical display format (combination of pie chart and segmented bar graph) was chosen over a single pie chart with 7 slices?
