The demand for a two-wheeler was 900 units and 1030 units in April 2015 and May 2015, respectively. The forecast for April 2015 was 850 units. Considering a smoothing constant of 0.6, the forecast for June 2015 is

1. 850 units
2. 927 units
3. 965 units
4. 970 units

Correct answer: 970 units

Solution

Using exponential smoothing with \(\alpha=0.6\), first compute the May forecast from April actual and forecast, then use the May actual to get the June forecast. This gives a June forecast of about 970 units. Therefore, the correct answer is 970 units.
