As you can see in the following table, demand for heart transplant surgery at Washington General Hospital has increased steadily in the pas few years: The director of medical services predicted 6 years ago that demand in year 1 would be $$44.0$$ surgeries. a) Using exponential smoothing with $$?$$ 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): For the forecast made using exponential smoothing with $$?=0.60$$ and the given forecast for year $$1,\mathrm{MAD}=3.9$$ surgeries (round your response to one decimal place). Using exponential smoothing with $$?$$ of $$0.90$$ and the given forecast for year 1 , the forecasts for years 2 through 6 are (round your responses to one decimal placel: Using exponential smoothing with $$?$$ 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): For the forecast made using exponential smoothing with $$?=0.90$$ and the given forecast for year $$1,MAD=3.1$$ 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): For forecasts made using a 3-year moving average, MAD = 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): For the forecast made using exponential smoothing with $$?=0.90$$ and the given forecast for year $$1,MAD=$$ 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); For forecasts made using a 3-year moving average, MAD $$=2.8$$ 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):
