Question

2.(26 total points) An experiment was conducted to study the effect of two factors: (1) the height of the bed (low and high) and (2) row spacing (0.25, 0.5, and 1 meter) on the moisture content (MC) of soils in which a plant variety was grown under a specific type of irrigation practice. The experiment was conducted on 18 plots, divided into 3 blocks of 6 plots each and the 6 combinations of the two factors were placed into each block. Use the irrigation data file posted on Canvas to do an appropriate analysis. o(4 points) Write out the appropriate statistical model and explain the terms. (b)(4 points) Determine the sources of variation and degrees of freedom and fill in the table below Source Degrees of Freedom e) (4 points) Construct an interaction plot where row spacing is the trace factor. Based on the plot, does there appear to be evidence of an interaction? a (4 points) Generate the ANOVA for the fixed effects and report the p-values for height, spacing, and the interaction term. Based on the p-values, should the analysis focus on main effects or simple effects?
