Based on your observation, does the data follow a linear pattern? (5 marks) - 12. While we used a line of best fit to calculate residuals earlier, you can actually use any model to calculate residuals and = 3.3x - 9.4x 0.1 to calculate a new set of residuals, using a formula create a residual plot. Use the estimate Yest or a calculator. Explain your steps, then create a residual plot using this new model and assess its validity. (6 marks)
