Given the actual demand for heart transplant surgery at a local hospital from year 1 to year 6:

Actual Demand	45	50	52	56	58	?

The current year is year 6. The director of medical service predicted 6 years ago that the predicted demand in year 1 would be 41 surgeries. Use exponential smoothing model with a smoothing constant of 0.60 to obtain the predicted demand (with 1 dec pl) in years 2,3,4,5. What would be the value of MAD for years 1,2,3,4,5? Use 2 dec pl.

Keep your written work.

Select one:

a. MAD = 1.06b. MAD = 8.66c. MAD = 13.36d. MAD = 22.66e. MAD = 5.06
