4. Driver Rufus keeps a record of a shift's worth of deliveries for BFD in the table below and then computes the sample statistics: if the number of servings are the {₁} data and the order cost is the {y} data, then I = 4.1250, ≈ 16.6213, S≈ 2.2321, Sy 7.4167, and the correlation coefficient is r≈ 0.9420. Build a linear regression model and use that model to predict the cost for an order that has 3 servings.5
