Consider your work on text problem 4.13. In this problem you were asked to calculate the the trend forecast for heart transplants over 6 time periods. Given this which of the following best represents the exponentially smoothed forecasted demand for heart transplants in year 6 using an alpha 0.9? (Rounded to the nearest integer- since it is impossible to give a part of a heart transplant!) 62 58 54 None of the above are within 1 of the solution 4.13 As you can see in the following tuit, uemand vor heart transplant surgery at Washington General Hospital has increased steadily in the past few years: 2 3 4 5 6 YEAR 50 52 56 58 45 2 HEART TRANSPLANTS The director of medical services predicted 6 years ago that demand in year I would be 41 surgeries. Condor 35/Shutterstock d ir a). Usc exponential smoothing: fins with smoothing constant of 6 and then with one of 9 to develop forecasts for years 2 through 6. b) Use a 3-year moving average to forecast demand in years 4, 5. and 6 c) Use the trend-projection method to forecast demand in years 1 through 6. d) With MAD as the criterion, which of the four forcatini le
