Question Set 2. Using only the Miami sales data:

1. Forecast sales for January 7^th through January 30^th using a three-day weighted moving average. (5pts)

The weights are:

Day	Weight
1 day previous	0.45
2 days previous	0.30
3 days previous	0.25

2. Find the mean absolute deviation of the sales forecasts for January 7^th through January 29^th. You should not include the forecast for January 30^th since there is no corresponding sales figure for that date. (3pts)

3. Find the mean squared error of the sales forecasts, again for January 7^th through January 29^th. (4pts)

4. Create a scatter scatter-chart for the three-day weighted moving average. Label your chart axes properly. (2 pts)
