For forecasts made using the trend-projection method, MAD= ______ surgeries (round your response to one decimal place)

D) based on the comparison of MAD, the best forecast is archived using the _____ method

As you can see in the following table, demand for heart transplant surgery at Washington General Hospital has increased steadily in the past few years: Year Heart Transplants 1 45.0 2 48.0 3 55.0 4 56.0 5 60.0 The director of medical services predicted 6 years ago that demand in year 1 would be 41.0 surgeries. a) Using exponential smoothing with a of 0.60 and the given forecast for year 1, the forecasts for years 2 through 6 are (round your responses to one decimal place): Year Forecast 1 41.0 2 43.4 3 46.2 4 51.5 5 54.2 6 57.7 For the forecast made using exponential smoothing with a = 0.60 and the given forecast for year 1, MAD = 5.5 surgeries (round your response to one decimal place). Using exponential smoothing with a of 0.90 and the given forecast for year 1, the forecasts for years 2 through 6 are (round your responses to one decimal place): Year 1 2 3 4 5 6 Forecast 41.0 44.6 47.5 54.1 55.6 59.4 For the forecast made using exponential smoothing with a = 0.90 and the given forecast for year 1, MAD = 4.2 surgeries (round your response to one decimal place). b) Forecasts for years 4 through 6 using a 3-year moving average are (round your responses to one decimal place): Year Forecast 4 49.3 5 53 6 57 For forecasts made using a 3-year moving average, MAD = 6.9 surgeries (round your response to one decimal place). c) Forecasts for years 1 through 6 using the trend-projection method are (round your responses to one decimal place): Year 1 Forecast 1 0 2 0 3 0 4 0 5 0 0 Enter your answer in the edit fields and then click Check Answer. 2 parts 2 Clear All Check Answer remaining
