The sample data are shown in Table below. Pharmacy Sales Volume, Y (in $ 1000) % of Ingredients Purchased Directly, X (in $1,000) 12510 25518 35025 47540 511050 613863 79042 86030 9105 1010055 Fit a suitable regression equation. How does the % of Ingredients Purchased Directly affect sales volume? If it is given that the % of Ingredients Purchased Directly for a pharmacy is $20,000, what would be the sales volume?
