SCENARIO 16-14 a Contractor Developed a Multiplicative Time-Series Model to Forecast the Forecast

Multiple Choice

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 2013.The following is the resulting regression equation:
ln Y^ˆ = 3.37 + 0.117 X - 0.083 Q₁ + 1.28 Q₂ + 0.617 Q₃
where
Y^ˆ is the estimated number of contracts in a quarter.
X is the coded quarterly value with X = 0 in the first quarter of 2011.
Q₁ is a dummy variable equal to 1 in the first quarter of a year and 0 otherwise.
Q₂ is a dummy variable equal to 1 in the second quarter of a year and 0 otherwise.
Q₃ is a dummy variable equal to 1 in the third quarter of a year and 0 otherwise.
-Referring to Scenario 16-14,in testing the coefficient of X in the regression equation (0.117) the results were a t-statistic of 9.08 and an associated p-value of 0.0000.Which of the following is the best interpretation of this result?

A) The quarterly growth rate in the number of contracts is significantly different from 0% ( α = 0.05) .
B) The quarterly growth rate in the number of contracts is not significantly different from 0% ( α = 0.05) .
C) The quarterly growth rate in the number of contracts is significantly different from 100% ( α = 0.05) .
D) The quarterly growth rate in the number of contracts is not significantly different from 100% ( α = 0.05) .
