Quizplus · Accepted Answer

The t-test statistic and F-test statistic are not necessarily equal when testing whether the number of customers who make purchases is a good predictor for weekly sales. The t-test statistic is used to test the significance of the regression coefficient for the predictor variable, while the F-test statistic is used to test the overall significance of the regression model. They are testing different aspects of the model and therefore can have different values.
