QUESTION 4
Suppose the following are the seasonal indices for the first three quarters of the year for a quarterly series:
Quarter
Seasonal Index
Q1
72.4
Q2
85.3
Q3
109.6
Remember that the seasonal indices should average 100 so you should be able to infer the seasonal index for Q4. Furthermore, suppose that the estimated coeffcients from a regression of the deseasonalized series on Time are given below:
Coefficients
Intercept
2,506
Time
71.3
If the original value of the series in a Q1 was 2,040, then what is the seasonally adjusted value? (please round your answer to 1 decimal place)
Question 2
Mr. Ferdinand is a well known entrepreneur who sells fresh organic beef to persons in the local
community. Customers love the quality of meet that Mr. Ferdinand sells so they tend to
recommend his product to other persons. Recently, Mr. Ferdinand has been running out of beef
to sell to his customers. One customer suggests to him that he must use past sales records to
forecast demand for his beef so that he can meet his customers demand.
I Using a numerical example, demonstrate to Mr. Ferdinand how he can use a three-
week and a four-week weighted moving average to forecast demand for his beef.
II. Show how Mr. Ferdinand can test the accuracy of his forecast.
II.
Explain to Mr. Ferdinand two ways in which he can benefit from doing forecast for
his beef.
