Table 3. Results of estimated coefficients (Model 1) Coefficients Unstandardized Coefficients Std. Error (Constant) Trend 183.000 3.893 13.381 2.992 a. Dependent Variable: Pass 13. The demand model is specified as: Ft a0 al *Trend, where Ft total air passenger-miles (billions) and Trend-a time trend. You collected data from Quarter 1 of 2006 to Quarter 4 of 2014 (36 observations) and obtained the coefficient results (Table 3). Forecast air passenger-miles for the 2nd quarter of 2015. (decimal places: 3)

In the above formula, the quarter 2 of 2015, the trend value would be 38,

So substituting in equation,

Ft = 183+3.893*38

= 330.934

So there would be 330.934 air passenger-miles
