The problem below looks at forecasting methodologies to determine which forecasting model results in the most accurate forecasts.  Accuracy is determined by the lowest mean absolute deviation.   Emergency calls to the 911 system of York County for the past 24 weeks are shown below.  Accurate forecasts are needed to determine the number of operators needed to staff the station.    Week # of Calls 1 50 2 35 3 25 4 40 5 45 6 35 7 20 8 30 9 35 10 20 11 15 12 40 13 55 14 35 15 25 16 55 17 55 18 40 19 35 20 60 21 75 22 50 23 40 24 65   SIMPLE LINEAR REGRESSION Use all of the data, weeks 1 - 24, to calculate the regression equation for this data.  Use the weeks (1-24) as the independent variable (x) and number of calls as the dependent variable (y).  Once you have the equation, forecast weeks 4 through 24 (enter 4, 5, 6,  etc. as the x…
