1) Chelsea wants to perform an irrigation experiment on the beefsteak tomatoes growing in her garden. The blocks are various locations within her garden. Six irrigation treatments are used in eight blocks of tomato vines. The data below are the weights (in pounds) of the harvested tomatoes from each plot.

What type of model should be used (e. g., fixed effects or random effects)? Write out the model with all constraints and distributional assumptions. Give the specic limits on all the indices. Describe all terms used in the model. d. Produce a highquality graph to compare the irrigation methods and a highquality graph to compare the blocks. Interpret the results from the graphs. Construct the analysis of variance table by hand (i.e., do not use R at all). Test for differences between the methods and differences between the blocks using a 5% signicance level (old method). g. Construct a Q-Q plot to examine the assumption of normality. Interpret the plot. PET?" H252
