A randomized block design was used to compare the mean responses for three treatments. Four blocks of three homogeneous experimental units were selected, and each treatment was randomly assigned to one experimental unit within each block. The partially completed ANOVA table for this experiment is as follows: Source df SS MS F Total 11 84.489 Treatments 2 12.032 6.016 Blocks 3 71.749 23.916 Error 6 0.708 0.118 Do the data provide sufficient evidence to indicate that blocking was effective in reducing variation in the responses? Use α = 0.05.
