When testing the overall significance of the regression model at the 5% level given a critical value of F_0.05, (2.20) = 3.49, the decision is to ___ reject H_0 and conclude that the explanatory variables ore jointly significant not reject H_0 and conclude that the explanatory variables are jointly significant reject H_0 and conclude that the explanatory variables are not jointly significant not reject H_0 and conclude that the explanatory variables are not jointly significant

Explanation / Answer

Obtain the F test statistic as follwos.

F=MSR/MSE=2.59

Reject null hypothesis, if p value is less than alpha=0.05. Here, p value is not less than 0.05, therefore, fail to reject null hypothesis and conclude that there is insufficient sample evidence to suggest that explanatory variables are jointly significant. Option 4 is correct.
