            Problem 1

                        The owner of Wine Sales & Service wants to forecast wine demand. Demand for the preceding four years is shown in the following table. Forecast demand for next year using:
                    
                        (i)	
                        Exponential smoothing with an alpha of 0.4 (Assume Yr. 1 forecast = 805).
                    
                        (ii)	
                        Calculate MAD
                    
                        (iii)	
                        Use solver to determine the best alpha to minimize the error (MAD)

            Problem 2

                        1.     The operations manager of a musical instrument distributor feels that demand for bass drums may be related
                    
                        to the number of television appearances by the popular rock group Green Shades during the preceding
                    
                          month. The manager has collected the data shown in the following table:
                    
                        Demand for Bass Drums	
                        Green  Shades TV Appearances

                        a). Use the least squares regression method to derive a forecasting equation. (Hint: you may use Data Analysis - Regression to get the slope and y-intercept)
                    
                        b). What is your estimate for bass drum sales if the Green Shades performed on TV nine times last month?
                    
            Problem 3

                        Using the appropriate control chart, determine two - sigma control limits for each case:
                    
                        (i)              An inspector found an average of 3.9 scratches in the exterior paint of each of the automobiles being prepared for shipment to dealers.
                    
                        (ii)            Before shipping lawn mowers to dealers, an inspector attempts to start each mower and notes any that do not start on the first try. 
                    
                            The lot size is 100 mowers, and an average of 4 did not start (4 percent).
                    
            Problem 4

                        John and Jane Doe make cherry crates for resale to local growers. 
                    
                        They and their four employees invest 50 hours per day making 150 crates.
                    
                        a).  What is their productivity?
                    
                        b).  They have discussed reassigning work so the flow through the shop is smoother.
                    
                               If they are correct and can do the necessary training, they think they can increase
                    
                               crate production to 155 per day. What would be their new productivity?
                    
                        c).  What would be their increase in productivity?

1. The operations manager of a musical instrument distributor feels that demand for bass drums may be related
to the number of television appearances by the popular rock group Green Shades during the preceding
month. The manager has collected the data shown in the following table:
