If the null hypothesis is rejected, use Tukey's test to determine which pairwise differences are significant using a familywise error rate of a = 0.05. Question (2): (10 points) A medical researcher wanted to determine the effectiveness of coagulants on the healing rate of a razor cut on lab mice. Because healing rates of mice vary from mouse to mouse, the researcher decided to block by mouse. First, the researcher gave each mouse a local anesthesia and then made a 5-mm incision that was 2 mm deep on each mouse. He randomly selected one of the five treatments and recorded the time it took for the wound to stop bleeding (in minutes). He repeated this process two more times on each mouse and obtained the results shown.
