A consulting firm estimates the following quarterly sales forecasting model: Qt=a+bt+cD The equation is estimated using quarterly data from 2010/2020 (t=1.... 43). The variable D is a dummy variable for the second quarter where: D=1 in the second quarter, and O otherwise. The results of the estimation are: DEPENDENT VARIABLE: QT R-SQUARE OBSERVATIONS: 43 0.8644 VARIABLE INTERCEPT T D PARAMETER ESTIMATE 22.50 1.86 2.00 F-RATIO 127.5 STANDARD ERROR 9.32 0.55 0.71 P-VALUE ON F 0.0001 T-RATIO P-VALUE 2.41 0.0201 3.38 0.0016 2.82 0.0075 Given the above, at the 1 percent level of significance, is there a statistically significant trend in sales?
