Week Number Demand 1 D1 2 D2 3 D3 4 D4 5 D5 6 D6

1. Manually type in 6 random whole numbers between the values of 10 and 100 in place of D1 through D6 in the above table. If the numbers are not random, you will lose credit. For example 10, 20, 30, 40, 50, 60 for D1 through D6 will not be considered a random set of demand values. Using the same sequence of numbers from posted exercises are also not considered random.

2. Create forecasts for weeks 4, 5 and 6 using the nave forecasting method.

3. Assume the forecast for week 3 is equal to D2. Create forecasts for weeks 4, 5 and 6 using the exponential smoothing method where alpha (i.e. ) = 0.5.

4. Which method is more accurate? Give quantitative justification as well as intuitive reasoning to justify your answer.
