All I really need is the yellow part. Most importantly which regressions and why

Apts] Problem #1) Hooke's law states that F= kx, where F s the force (N) used to stretch a spring and x is the increase in its length (mm). You conducted an experiment on Hooke's law in physics lab. After the experiment, you realized that the spring scale you used was defected. As the result, your force data contained errors. By hand calculation, find the best-estimated" value for the spring constant, k, for the given set of data in Table I. Make sure that k has the right unit Clearly state which regression method you used and the reason why, and also show the re gression equation Calculate the root- mean-square error, RMS. Then, use MATLAB to plot the points [xk, Fk] and the line using the calculated k value on the same graph Table I Spring stretch and applied force xk (mm) 0 24 6 9 11 12 15 17 19 FkN 5 6 7 6 987 10 12 12
