Quizplus · Accepted Answer

The statistical significance of a regression model is tested using an F-test, which examines the variance explained by the model compared to the variance not explained. The t-test is used to test the significance of individual coefficients in the model, and the Z-test is used for hypothesis testing of population means when the sample size is large. Option B appears to be a typing error.
