Chapter 8, Section 2, Exercise 053
Peanut Butter vs Ham & Pickles
The ANOVA table for the SandwichAnts data below
indicates that there is a difference in mean number of ants among
the three types of sandwich fillings. We know that the difference
is significant between vegimite and ham & pickles, but not
between vegemite and peanut butter. What about peanut butter vs ham
& pickles? Test whether the difference in mean ant count is
significant (at a 5% level)...
