Between 495.34                  4                           123.84                             8.16

Within      682.56                45                           15.17

Total        1,177.90               49

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

Please let me know if you need any clarification. I'm always happy to answer your questions.
