(b) what is the conclusion of the test? use a 5% significance level. (c) if in part (b) you determined that the test is significant, conduct pairwise tests to determine which groups are different from each other. if you did not reject the null hypothesis in part (b), recheck your answer. summary statistics for each group are provided below mean sd n tr 3 -3.21 8.57 14 14 14 tr 1 6.21 12.3 tr 2 2.86 7.94
