Detailed explanation-1: -The F-statistic and associated p-value in the ANOVA table is used for testing whether all of the slope parameters are 0. In most applications, this p-value will be small enough to reject the null hypothesis and conclude that at least one predictor is useful in the model.
Detailed explanation-2: -An F test is used to test the hypothesis that the values of the regression parameters 1, 2, . . ., q are all zero.
Detailed explanation-3: -The null hypothesis that any particular partial regression coefficient (i) equals zero can be tested with a t-test or with a partial F-test. t is the estimated t-statistic; under the null hypothesis it is a random quantile of the t-distribution with (n − p) degrees of freedom.
Detailed explanation-4: -The F-test of overall significance indicates whether your linear regression model provides a better fit to the data than a model that contains no independent variables.
