7) I ran an ANOVA CRD, F-test to test the claim that the four different drugs all produce the same average number of hours of sleep. We were able to reject that claim, so we then made pairwise comparisons. Use the pairwise comparisons below to put the means in order from lowest to highest, be sure to draw a line above the means that are not significantly different.
A - B (19, 25)
A - C (-2, 4)
A - D (16, 22)
B - C (-19, -13)
B - D (-5, 2)
C - D (8, 14)
