Explain The number of heart surgeries performed at Heartville General Hospital has increased steadily over the past several years. The hospital’s administration is seeking the best method to forecast the demand for such surgeries in year 6. The data for the past five years are shown below. Year 4 44 60 1 2 3 5 Demand 49 52 57 The hospital’s administration is considering the following forecasting methods. Begin error measurement in your 3, 00 all methods are compared for the same years. 1. Exponential smoothing, with a = 06. Let the initial forecast for year 1 be 44, the same as the actual demand. II. Exponential smoothing, with a = 0.9. Let the initial forecast for year 1 be 44, the same as the actual demand ill. Trend projection with regression Iv. Two-year moving average i Two-year weighted moving average, using weights 0.6 and 0.4, with the more recent data given more weight of MAD is the performance criterion chosen by the administration, which forecasting method should it choose? Exponential smoothing with a 0.6 Exponential smoothing with 0.9 Trond projection with regression Two-year moving average Two year weighted moving average
