Final answer:
The forecast for period 7 using a four-period moving average is 17625.
None of the given options is correct
Step-by-step explanation:
To calculate the forecast for period 7 using a four-period moving average, we need to consider the four previous periods: periods 3, 4, 5, and 6.
Given the data set E1:
Period Sales Volume
1 10000
2 12400
3 14250
4 15750
5 20500
6 18500
7 15750
8 20500
9 21500
10 22550
To find the forecast for period 7, we calculate the average of the sales volume for periods 4, 5, 6, and 7.
Step-by-step calculation:
- 1. Add up the sales volumes for periods 4, 5, 6, and 7: 15750 + 20500 + 18500 + 15750 = 70500.
- 2. Divide the sum by 4 (since we are using a four-period moving average): 70500 / 4 = 17625.
Therefore, the forecast for period 7 using a four-period moving average is 17625.
None of the provided options match the calculated forecast of 17625.
Your question is incomplete, but most probably the full question was:
Using the given data set, compute the above calculation to find the answer.
Period Sales Volume 10000 12400 14250 15750 20500 18500 15750 20500 21500 22550
Using the Data Set E1, what would be the forecast for period 7 using a four period moving average:
a. 14250
b. 15750
c. 20500
d. 18500
