C. 1. For the illustrative example discussed in Section C. 10 the XX and X'y using the data in the deviation form are as follows: , _ 1,103,111.333 16,984 XX[ 16,984 230] X, _ 955,099,333 3" 14,854.000 a. Estimate ,6; and 133. b. How would you estimate 131? c. Obtain the variance of fig and 53 and their covariances. d. Obtain R2 and R2. 3. Comparing your results with those liven in Section C. 10, what do you nd are the advantages of the deviation form
