Question

A statisical experiment is run on a machine that makes paper bags. The settings of dial A and dial B effect the quality of the bags. We use the regression model z = qx + ry+ s, where z is the quality of a bag, x is dial A's setting, y is dial B's setting.

We use the regression model z = qx + ry + s, where z is the quality of a bag, x is dial A's setting, y is dial B's setting. The results of the experiment are z 4 5 9 8 4 x 0 4 -2 0 -2 y 0 1 -1 -3 3 For the regression model P = qA + rB + s1, find the pseudoinverse of coefficient matrix A for q,r and s (recall that s's column is all 1's), and then find the values of the regression coefficients q, r, and s What is the correlation coefficient between x and z
