2.1) Use 3-period moving average method (with the general equation given below) to calculate:
2.1.1) the number of Product 1 ABC may plan to sell in Week 6.
2.1.2) the predicted number of Product 2 that ABC planned to sell in Week 5.
2.2) A local competitor, Company XYZ sells Product 5, another type of computer monitor. Product 5 of
XYZ typically takes 20% of the total market and the 4 types of products of ABC together take 80% of
the market. ABC would like to use its own data to estimate the number of Product 5 sold by XYZ. Use
4-period moving average method to calculate the number of Product 5 that XYZ may have sold in
Week 5.
To calculate Moving Average with n periods: X, =
