The historical demand for the Panasonic Model 304 Pencil Sharpener is: January, 60; February, 80; March, 75; April, 95; and May, 90 units.
- Using a four-month moving average, what is the forecast for June? If June experienced a demand of 100, what is the forecast for July?
- Using single exponential smoothing withα = 0.2, if the forecast for January had been 70, compute what the exponential forecast would have been for the remaining months through June.
- Develop a linear regression model and compute a forecast for June, July, and August.
