Computational (Tucker 5.3.3) Consider the following data on the number of accidents involving bus drivers as a function of the years of experience: Years of experience 2 4 6 8 10 12 Accidents per 1000 drivers 1 8 3 8 4 5 (a) Fit these data to a regression model of the form y = qr +r, where r describes years of experience and y is the number of accidents per year per 1000 drivers. Determine q and r by computing the pseudoinverse of a matrix, X, whose first column contains the r; values and whose second columns is all ones, then multiplying the result by the vector of y; values, X+7. Use MATLAB for your calculations. (b) Shift the values of x to by a constant to make their average 0, then repeat (a). How do the results from these two calculations differ
