Compute a 4-quarter moving average forecast for qtr. 3 of year 5 (round to the nearest unit)

2). compute a 3-quarter weighted moving average forecast for quarter 3 of year 5. use these weights: 7 on the prior quarter, and then 4 and 1 (respectively) on quarters prior to that (rounded to the nearest unit).

3). use exponential smoothing method with ? = 0.33 to forecast demand in quarter 3 of year 5. assume forecast for q1 of year 1= 24,850. round off the final answer to nearest integer

4). examine the 3 methods you used in the previous 3 problems. which is best to use for this time series?
