A professor has a class with four recitation groups. Each section has 16 students. Determine whether or not the section choice (different TAs and different days of the week) has any relationship with how students performed on the test. First, run an ANOVA with this data and fill in the summary table. (Report P-values accurate to 4 decimal places and all other values accurate to 3 decimal places.) To follow-up, the professor decides to use the Tukey-Kramer method to test all possible pairwise contrasts. What is the Q critical value for the Tukey-Kramer critical range (alpha=0.05)? Use the table below to locate the \( Q \) critical value to 4 decimal places. \( Q= \) Using the critical value above, compute the critical range and then determine which pairwise comparisons are statistically significant? group 1 vs. group 2 group 1 vs. group 3 group 1 vs. group 4 group 2 vs. group 3 group 2 vs. group 4 group 3 vs. group 4 none of the groups are statistically significantly different
