1. For the same data, two sets of forecasts are made, one using exponential smoothing with alpha = 0.2 and the other with alpha = 0.8.

With the higher value of alpha, the forecasts will:

a. Be more responsive to actual demand

b. Be more accurate

c. Not change much from period to period

d. Give less weight to the most recent period compared to other periods

2. Based on 3 years of data, the quarterly demand for a product has a trendline with the equation 150 + 8*Period. The seasonality indexes for the four quarters are: 0.8, 1.1, 1.2, and 0.9 respectively.

It is now the end of quarter 4 (period 12). What is the forecast for quarter 2 of next year? Round to closest integer.

a. 190

b. 288

c. 140

d. 334

3. Monthly demand for a product has an upward trend. The trendline describing this behavior has the following equation:
