WebThe null hypothesis of the linear model is that \(\beta_1\) and \(\beta_2\) are both zero; or equivalently, that all groups have the same mean of \(\beta_0\).To test this hypothesis, an F-test is used. The F statistic in a regression is the result of a test where the null hypothesis is that all of the regression coefficients are equal to zero.
