C) An analyst must decide between two different forecasting techniques for weekly sales of roller blades: a linear trend equation and exponential smoothing. The linear trend equation is Ft = 124 + 2t, and it was developed using data from periods 1 through 10. Based on data for periods 11 through 20 as shown in the table, which of these two methods has the greater accuracy if MAD and MSE are used? exponential smoothing with an alpha of 0.3 and forecast of period 11 is 148 11 12 13 14 15 16 17 18 19 20 Units Sold 147 148 151 145 155 152 155 157 160 165 D) A manager is using the equation below to forecast quarterly demand for a product: Yt = 6,000 + 80t where t = 0 at 02 of last year Quarter relatives are Q1 = 0.6, Q2 = 0.9,23 = 1.3, and 04 = 1.2. What forecasts are appropriate for the last quarter of this year and the first quarter of next year
