What level of confidence can you have in
rejecting the null hypothesis?
Thank you for the opportunity to help you with your question!
F(0.05,4,45)=2.579 but calculated F=8.16, therefore we reject the null hypothesis since the test statistics is much larger than the critical value.
hence the level of confidence is 0.95
