Write out the ANOVA shell (sources of variability & degrees of freedom) for each of the following experiments described below. Identify all factors in the ANOVA that should be treated as random in the analysis. a. (10 pts.) A 3-way factorial treatment structure was run in a balanced CRD. Treatment factor A has 3 levels, factor B has 2 levels and factor C has 4 levels. Every combination of A, B and C has 3 replicates. b. (10 pts.) An RCBD with 8 blocks has a 2-way factorial treatment structure consisting of treatment factor A with 3 levels and treatment factor B with 4 levels.
