SCENARIO 16-14
A contractor developed a multiplicative time-series model to forecast the number of contracts in
future quarters, using quarterly data on number of contracts during the 3-year period from 2011 to
-Referring to Scenario 16-14, to obtain a forecast for the fourth quarter of 2014 using the model, which of the following sets of values should be used in the regression equation? a) $X = 15 , Q _ { 1 } = 0 , Q _ { 2 } = 0 , Q _ { 3 } = 0$
b) $X = 15 , Q _ { 1 } = 1 , Q _ { 2 } = 0 , Q _ { 3 } = 0$
c) $X = 16 , Q _ { 1 } = 0 , Q _ { 2 } = 0 , Q _ { 3 } = 0$
d) $X = 16 , Q _ { 1 } = 1 , Q _ { 2 } = 0 , Q _ { 3 } = 0$
