4. Given the following data for a post test in Algebra Knowledge among 3 different teachers in a school district, the following raw data is shown: Teacher 1 Teacher 2 Teacher 3 88 77 60 85 75 66 Is there a significant difference among the means of Algebra Knowledge across the independent factor of teacher? If so, which pairs of pairwise differences are significant. Again, all of this is at the .05 error level. Set up the null and alternate hypotheses. Perform all relevant calculations, create your ANOVA table. Do you retain or reject the null? When you are done with the Omnibus ANOVA, if necessary, use the Tukey post hoc test. Perform the necessary calculation if applicable, and then identify the significant pairwise contrasts.
