Suppose the following are the seasonal indices for the first three quarters of the year for a quarterly series: 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 coefficients from a regression of the deseasonalized series on Time are given below: If the original value of the series in a Q4 was 2494, then what is the seasonally adjusted value? (please round your answer to 1 decimal place)

Suppose the following are the seasonal indices for the first three quarters of the year for a quarterly series:  Quarter Seasonal Index Q1 70.3 Q2 81.4 Q3 107      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 2,345 Time 62.4  What is the forecast for period 104, if period 104 is a Q4? (please round your answer to 1 decimal place

Suppose the following are the seasonal indices for the first three quarters of the year for a quarterly series:  Quarter Seasonal Index Q1 73.7 Q2 82.5 Q3 108.1      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 2,733 Time 65.8  If the original value of the series in a Q4 was 2,197, then what is the seasonally adjusted value?

Which of the following is a DISADVANTAGE of using a moving average technique todetermine time series trend?A.The trend values obtained do not reflect thegeneral trend.B.Only one trend value can be obtained foreither of the end points of the series.C.No trend values are obtained for thebeginning and end time points of the series.D.Each moving average trend value obtaineddoes not correspond with a time point
