Solve the following: 1. Sales of Volkwagen’s popular Beetle have grown steadily at auto dealership in Nevada during the past 5 years (see table below). The sales manager had predicted before the new model was introduced that first-year sales would be 410 VWs. Using exponential smoothing with a weight of α= .30, develop forecast for years 2 through 6. Year Sales 1 450 410 2 495 3 518 4 563 5 584 6? 2. The following data come from regression line projections: Forecast Period 1 2 3 4 Forecast Values 410 419 428 435 Actual values 406 423 423 440 Compute the MAD and MSE.
