Quarter	Seasonal Index
Q1	73
Q2	82.8
Q3	107.8

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	2,494
Time	64.6

What is the forecast for period 69, if period 69 is a Q4? (please round your answer to 1 decimal place)
