17. a) Given the following scatter plot and line of best fit, sketch a residual graph below. Recall: Residual = actual data - predicted value [3 marks] Output 225 2010- 17.5 15.0 12.5- 10.0 7.5 50- 10 13 Input 0 2 4 10 12 Remember that the horizontal (x) axis will be the same for the residual plot and the original graph, but the y axis will be different. b) Based on the residuals plot, is a line a good fit of the data? Explain why or why not based on what you learned about residuals in class. [2 marks] 17. a) Given the following scatter plot and line of best fit, sketch a residual graph below.
