Explanation / Answer

Solution:-

Null hypothesis: The fit of the intercept-only model and our model are equal.

Alternative hypothesis: The fit of the intercept-only model is significantly reduced compared to our model.

Signifucance value = 0.05

DFnumerator = 6

DFdenominator = 5

F = 15.81

p-value = 0.0041

Since the P value for the F-test of overall significance test is less than your significance level, we can reject the null-hypothesis and conclude that our model provides a better fit than the intercept-only model.
