Check my work Problem 3-34 points A manager uses a trend equation plus quarterly relatives to predict demand. Quarter relatives are SR = 0.9, SR2 = 0.95, SR3 = 1.05, and SR4 = 1.1. The trend equation is: Ft= 10 + 3t. Over the past nine quarters, demand has been as follows: eBook Print Period, t: Demand: 1 2 3 4 5 6 7 8 9 15 17 19 23 25 27 32 36 41 References Compute the MAD and tracking signal for each period. (Negative values should be indicated by a minus sign. Round your intermediate calculations and final answers to 3 decimal places.) Period, t Demand MAD Tracking signal 19
