2. Let y1, 12, .... Un are outcome measures from a dependent variable such that yi = Bo+ Birite Suppose the GM conditions are satisfied. a. Show that y, and y, are uncorrelated b. Let 3, and 3, be the least square estimators (LSEs) for Bo and 1, respectively. Show that the predicted values y; are uncorrelated with the residuals r; = y - yi c. Now assume that 6 ~ NV(0. o'), show that the predicted val- ues and the residuals are independent
