Quizplus · Accepted Answer

The t test statistic and F test statistic are not the same 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 number of customers, while the F test statistic is used to test the overall significance of the regression model.
