Pet preference was compared for four different types of animals (dogs, cats, birds,
and fish), using a one-way within-groups ANOVA with seven participants. The
standard error was calculated as 0.21. What is the Tukey HSD value when comparing
data for dogs and cats given the following means for preference: Dogs M = 4.43, Cats
M = 4.18, Birds M = 2.73, Fish M = 4.07?
