(c) Use a calculator to verify that S. `x = 60, Sx² = 954, ) y = 640, y² = 91,850, and xy = 9,180. Compute r. As x increases from 3 to 21 months, does the value of r imply that y should tend to increase or decrease? Explain your answer. First, we construct a computation table so that we can calculate the values of x2, y2, and xy. Then we sum each column to compute each summation. y x2 y2 ху 3 60 9 3600 6 95 36 9025 570 12 140 144 1680 18 165 324 2970 27,225 32,400 21 180 441 3780 Sx = 60 = 640 Sxy = 954 %3D
