 Statistics II regression equation Cincinnati Paint Company sells quality brands of paints through hardware stores throughout the United States. The company maintains a large sales force whose job it is to call on existing customers as well as look for new business. The national sales manager is investigating the relationship between the number of sales calls made and the miles driven by the sales representative. Also, do the sales representatives who drive the most miles and make the most calls necessarily earn the most in sales commissions? To investigate, the vice president of sales selected a sample of 25 sales representatives and determined: • The amount earned in commissions last month (Y)• The number of miles driven last month (X1)• The number of sales calls made last month (X2) The information is reported below. Commissions    Calls         Driven   (\$000)      22          139            2,371   13         132            2,226   33         144            2,731   38         142            3,351   23         142            2,289   47         142            3,449   29         138            3,114   38         139            3,342   41         144            2,842   32         134            2,625   20         135            2,121   13         137            2,219   47         146                 3,463            38          146            3,29044          144            3,10329         147            2,12238         144            2,79137         149            3,20914         131            2,28734         144            2,84825         132            2,69027         132            2,93325         127            2,67143         154            2,98834          147            2,829 Develop a regression equation including an interaction term.
