An instructor wishes to determine whether there is any difference in three methods (1, 2, or 3) of teaching an elementary statistics course, with
regards to the final averages. Students in three different sections of the course were taught using one of the methods. Assume all other variables
remain fixed (eg. common exams, etc.). A preliminary sample of the overall course averages from the three sections is given in the following table
along with the ANOVA table. If you were testing at the 5 percent level of significance for the equality of the means for the different methods,
the rejection region will be
