Mean pairConfidence 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.
