 Mean pair Confidence interval $$\style{font-family:Times New Roman;}{\mu_2-\mu_1}$$ (–134.35, 22.68) $$\style{font-family:Times New Roman;}{\mu_3-\mu_1}$$ (–360.51,–195.82) $$\style{font-family:Times New Roman;}{\mu_4-\mu_1}$$ (–360.68,–203.65) $$\style{font-family:Times New Roman;}{\mu_3-\mu_2}$$ (–304.68,–139.99) $$\style{font-family:Times New Roman;}{\mu_4-\mu_2}$$ (–304.85,–147.82) $$\style{font-family:Times New Roman;}{\mu_4-\mu_3}$$ (–86.35, 78.35)

The table provides a group of 95% simultaneous Bonferroni confidence intervals. Which mean pairs (if any) appear to differ and how?

$$\style{font-family:Times New Roman;}{\mu_2>\mu_1\;}$$and$$\style{font-family:Times New Roman;}{\;\mu_2>\mu_3\;}$$and $$\style{font-family:Times New Roman;}{\;\mu_4>\mu_1}$$

$$\style{font-family:Times New Roman;}{\mu_2>\mu_1\;}$$and$$\style{font-family:Times New Roman;}{\;\mu_4>\mu_3}$$

$$\style{font-family:Times New Roman;}{\mu_1>\mu_3\;}$$and$$\style{font-family:Times New Roman;}{\;\mu_1>\mu_4\;\text{and}\;\mu_2>\mu_3\;}$$and$$\style{font-family:Times New Roman;}{\;\mu_2>\mu_4}$$

None of the mean pairs appears to differ.
