Final answer:
To forecast for May using a four-month moving average, you would take the average of the data from January to April.
Step-by-step explanation:
To determine the forecast for May using a four-month moving average, one would typically use the data from the four months leading up to May. In forecasting, a four-month moving average is a method used to analyze and predict future values based on the average of the previous four months. To forecast for May using a four-month moving average, you would take the average of the data from January to April. Here's an example:
- January: 5.4
- February: 4.4
- March: 3.4
- April: 2.9
To find the forecast for May, you would sum up these four values and divide by four: (5.4 + 4.4 + 3.4 + 2.9) / 4 = 4.525. So, the forecast for May using a four-month moving average is approximately 4.525.
