The table below shows the quarterly exports (in $ millions) from eight fictional towns in North America over a two-year period.

a. Construct a time-series graph for one of the cities. Looking at your graph, what are some of your insights and conclusions regarding this city’s exports over the two years?

b. Construct one graph that displays the eight quarters of data for each city separately but in the same graph so that you can compare the eight cities. What insights and/or conclusions about the exports of these cities do you have now that you can see all five in one graph?
