Demand for a newly introduced toy is as following: Period 1 through 12. At 1= 557; 2= 546; 3 =566; 4= 562; 5= 582; 6 =566; 7 =565; 8 =579; 9= 589; 10= 608; 11= 580; 12= 603. Using trend projection (simple regression), forecast for period 13 through 15. Using the trend projection equation, forecast for period 1 through 12, and calculate MAD. Based on your analysis of MAD, what conclusion would you draw for forecasts 13 through 15?
