Question 5 UVB & Toads Revisit _ 9 points Continue the Toads & UVB exposure study in Question 2 of Midterm Part 1. Recall the 6 treatment groups each have n = 4 observations. Below are the treatment means ij. and the MSE. UVB Water Depth 1=10 cm 2=50 cm 3=100 cm Row Mean E = Exposed 0.425 0.728 0.785 0.646 = S Shielded 0.759 0.748 0.767 0.758 MSE 6 treatments 4 observations per treatment = 0.005411 Column Mean 0.592 0.738 0.776 0.702 6 x 4 = 24 observations in total Q5a - 6 points Please calculate Tukey's Honest Sigificant Difference (Tukey's HSD) required to keep FWER at 0.05, and use it to do pairwise comparisons between the 6 treatments. Summarize the result with an underline diagram. Use 1E, 2E, 3E, 1S, 2S, and 3S as the treatment labels in the underline diagram. Please show your calculation and R codes if any. Q5b - 3 points Recall in Q2f in Midterm Part 1, we used the LSD to perform pairwise comparisons between the 6 treatments. What's the advantage of using Tukey's HSD over LSD? Explain briefly.
