TABLE 16-12 A Local Store Developed a Multiplicative Time-Series Model to Forecast

TABLE 16-12
A local store developed a multiplicative time-series model to forecast its revenues in future quarters,using quarterly data on its revenues during the 5-year period from 2008 to 2012.The following is the resulting regression equation:
log₁₀
= 6.102 + 0.012 X - 0.129 Q₁ - 0.054 Q₂ + 0.098 Q₃
where is the estimated number of contracts in a quarter
X is the coded quarterly value with X = 0 in the first quarter of 2008
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 is a dummy variable equal to 1 in the third quarter of a year and 0 otherwise
-Referring to Table 16-12,in testing the significance of the coefficient for Q₁ in the regression equation (-0.129) which has a p-value of 0.492.Which of the following is the best interpretation of this result?

A) The revenues in the first quarter of the year are significantly different from the revenues in an average quarter (α = 0.05) .
B) The revenues in the first quarter of the year are not significantly different from the revenues in an average quarter (α = 0.05) .
C) The revenues in the first quarter of the year are significantly different from the revenues in the fourth quarter (α = 0.05) .
D) The revenues in the first quarter of the year are not significantly different from the revenues in the fourth quarter (α = 0.05) .
