Using the GPRC and salary survey data provided above (i.e. the first two tables, not the third), construct a line chart that displays GPRC's pay structure relative to the external market. In your chart, create two lines for the external market. The first external market line should include survey data from all sources. The second external market line should include data from all sources except the Bureau of Labor and Statistics (BL5). Be sure to use weighted averages to create your market lines. I have included a sample chart below to give you a better understanding of what I want you to produce. The gray, blue, and orange lines on the chart are based on completely different data. However, your X axis should display Pay Grades 1 through 8 and your Y axis should be in dollars
