The regression analysis found a strong linear relationship between quarterly sales (y) and time (t). The model predicts y=95+29*Qtr1+57*Qtr2+26*Qtr3. Qtr1, Qtr2, and Qtr3 were all statistically significant predictors of sales. The R-squared value was 0.7988, indicating the model explains approximately 80% of the variation in quarterly sales.
