Scenarios 2 has 6 blocks. Consider the following two scenarios involving 24 pots and four treatment groups (three fertilizers and a control group). The images illustrate how the treatments were assigned to the pots. The research question of interest is whether the mean yields of the treatment groups are equal or not. (a) If Yij represents the i th pot receiving the j th treatment, write the ANOVA model for each scenario above. (b) Explain how the randomization of treatments to pots is different between the two scenarios. (c) Give the sources and degrees of freedom in the ANOVA table for each scenario. Note: since no data is provided, you don't have to calculate any sum of squares
