The file S03_53.xlsx lists campaign contributions, by number of contributors and contribution amount, by state (including Washington DC) for the four leading contenders in the 2008 presidential race. Create a scatter plot and corresponding correlation between Dollar Amount (Y axis) and Contributors for each of the four contenders. For each scatter plot, upper impose a linear trend line and show the corresponding equation. Interpret each equation and compare them across candidates. Finally, identify the state for any points that aren’t on or very close to the corresponding trend line.
