QUESTION 28

Suppose the following are the seasonal indices for the first three quarters of the year for a quarterly series:

Quarter	Seasonal Index
Q1	72.2
Q2	87.1
Q3	106

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	1,993
Time	75.3

What is the forecast for period 62, if period 62 is a Q1? (please round your answer to 1 decimal place)
