In R:

K = Create the following matrix: 3 1 33 4 3 4 -5 -1 -2 (a) (10 points) Find Q = K3 and P = KTK. (b) (5 points) Report the difference between the sum of second column of K and mean of second row of K. (c) (5 points) Replace the third row of K by the sum of the first column and third row. So the 1st item should be K[1,1] + K[3,1], 2nd item should be K[2, 1] + K[3,2], and the 3rd item should be K[3, 1] + K[3,3]
