Step 4 -92,850, and (c) Use a calculator to verify that ΣΧ-56, ΣΧ2-826, Σ y·642. Σ y, xy 8.604. 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. 3600 9025 12 14 21 60 95 140 159 188 36 144 196 570 1680 2226 3948 25,281 35,344 441 X-56
