The next 3 questions refer to the following data set. Show any relevant calculations or spreadsheet formulas that you used while responding to the questions. Years 0.9 2.0 2.1 4.0 4.8 5.2 6.2 9.0 9.1 Height (cm) 0.79 3.98 4.81 11.41 29.72 24.2 26.81 91.47 129.45 3. Use automatic linear regression (e.g. using Excel or Sheets) to find a line of best fit, with the Years as the "x" values and the Height (cm) as "y" values. Explain exactly what you did. (4 marks) 4. Find the correlation coefficient and coefficient of determination for the data. Assess how well the line fits the data. (5 marks) 5. Create a residual plot for the data using your line of best fit. What conclusions can you draw from the residual plot? (4 marks)
