Question
An experiment was carried out to compare electrical resistivity for six different low-permeability concrete bridge deck mixtures. There were 26 measurements on concrete cylinders for each mixture; these were obtained 28 days after
casting. The entries in the accompanying ANOVA table are based on information in an article. Fill in the remaining entries. (Round your answer for f to two decimal places.)

O Ho: H1 = H2 = H3 = H4= Hs=Hs
H: all six u,'s are unequal
O Ho: H1 # Hz # Hz# H4# Hs# HG
H: at least two u's are equal
H: all six u,'s are equal
O Ho: H1 = H2 = H3 = H4 = Hs= H6
