Multiple Comparisons (Bonferroni & Tukey HSD) with Confidence Intervals

Exercise:
  Twenty atopic dermatitis patients were randomly allocated into 2 groups (baseline), and a therapeutic drug or placebo drug was administered to treat itching sensation. The levels of the itching sensation at pre- and post-treatment were assessed by the 5-level itching evaluation score, which were 0, 0.25, 0.5, 0.75, and 1 from mild to severe itching sensation. The results are shown in the following table.
    A1 is placebo drug and A2 is the therapeutic drug. X represents pre-treatment score, and Y represents post-treatment score, respectively. Draw a graph of 2 groups, where X- and Y-axes indicate pre-treatment and post-treatment scores, respectively, and also analyze the difference in Y values (post-treatment scores) between groups.
