Task P2 Given the following set of data: 16 70 X y 7 17 26 248 38 555 50 630 62 783 77 886 86 967 a) Plot the data set as black diamonds. b) Use 'polyfit' function in MATLAB, to calculate the 'linear' line of best fit, coefficients 'a0' and 'a1' and the coefficient of determination, r². Print these values using fprintf. c) Use the 'polyval' function to interpolate/extrapolate to find the values of y for values of x corresponding to: 20, 40 and 80. Plot the extrapolated data points as red asterisks on the figure produced in part (a).
