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...
