Expert Solution

The model that we want to estimate is

from this

The estimated regression equation is

The hypotheses to Perform a test of the overall model, is

The test statistic is given in the ANOVA output

ans: The test statistic is F=187.56

The p-value is 0.0000 (rounded to 4 decimals) (from the significance F)

We will reject the null hypothesis if the p-value is less than the significance level.

Assuming a significance level of , we can say that the p-value is less than the significance level. Hence we reject the null hypothesis

ans: We conclude that the overall model is significant.
