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: logloi> = 6.102 + 0.012 X - 0.129 01 - 0.054 Q2 + 0.098 03 where f' is the estimated number of contracts in a quarter X is the coded quarterly value with X = 0 in the rst quarter of 2008 Q1 is a dummy variable equal to 1 in the rst 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 The estimated quarterly compound growth rate in revenues is around 0 12%. o 1.2%. o 2.8%. O 28%. 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: log10Y = 6.102 + 0.012 X - 0.129 Q1 - 0.054 Q2 + 0.098 Q3 where Y 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 Q3 is a dummy variable equal to 1 in the third quarter of a year and 0 otherwise In testing the significance of the coefficient of X in the regression equation (0.012) which has a p- value of 0.0000. Which of the following is the best interpretation of this result? O The quarterly growth rate in revenues is not significantly different from 1.2% (a = 0.05). O The quarterly growth rate in revenues is significantly different from 0% (a = 0.05). O The quarterly growth rate in revenues is significantly different from 1.2% (a = 0.05). O The quarterly growth rate in revenues is not significantly different from 0% (a = 0.05)
