A. Find the residuals.
B. Create a residual plot of the data.
C. Based on the residual plot, does the line y = 3.5x + 20 fit the data well? Explain
your reasoning.
3.5x+ 20 from Part C
D. Compare the sum of squared residuals for the line y
and the line y = 3.5x + 15.5. Which line fits the data better? Explain your
reasoning.
