3. 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 {$2} data and the order cost is the {y,-} data, then E = 4.1250, 37 % 16.6213, 8,, z 2.2321, 8,, m 7.4167, and the correlation coefcient is r m 0.9420. Build a linear regression model and use that model to predict the cost for an order that has 3 servings.4 servings 1 2 2 4 5 6 6 7 cost 3.43 12.25 9.89 20.85 17.87 22.71 20.85 25.12
