Health statistics
Using complete sentences, answer the following questions from your analysis:
What is the mean weight change for each of the three weight loss program groups (in pounds)?
What is the F test statistic value from the ANOVA that you performed in SPSS?
You have set your significance level at α=0.05 and performed a one-way simple ANOVA. Using this information and the two sets of degrees of freedom from your SPSS output, what is the critical F value for your test?
(Hint: use Table B.3 in Appendix B in your textbook. If you don’t see the exact number of degrees of freedom in your textbook, select the critical F value that corresponds to the closest number of degrees of freedom.)
Does your F test statistic value exceed the critical F value? What can you conclude about the three weight loss programs as a result?
Discuss the null hypothesis in your answer, and whether you reject or fail to reject it
