Question 2: Linear regression ( 30 points) Recall that the resistance R of an cylinder is R=AL where rho is the resistivity of the material, L is the length, and A is the cross-sectional area of the cylinder. Consider a sample of extrinsic silicon, from which 4 different cylinders are cut. The resistance and dimensions of these four cylinders are measured as: Use linear regression to calculate the resistivity of this sample of silicon. Check using your introduction to materials science textbook or Google to see if the number you obtain is reasonable. (I wouln't trust ChatGPT, but you may try that as well.) Make a plot that shows the 4 data points, as well as the line you fit
