For the data below, the regression model Y = 19.4340 +0.1068X, +0.0012X, uses sales (in thousands of dollars) and the number of orders received to predict distribution cost (in thousands of dollars). Develop an distribution cost that includes sales, orders, and the interaction of sales and orders. Complete parts (a) and (b) below. E Click the icon to view the data. a. At the 0.01 level of significance, is there evidence that the interaction term makes a significant contribution to the model? Let the interaction variable be X.
