Question
da Silva-Castiglioni et al. (2010) investigated the effect of various diets on the
biochemical composition of Hyalella bonariensis. In one part of the analysis, males of
the species were subjected to 5 different diets for 45 days, then researchers
measured the levels of lipoperoxidation.
The researchers carried out a one-way ANOVA, and found a p-value of 0.00022.
After that, they decided to apply the Tukey procedure to find confidence intervals for
the pairwise differences in means at a family-wise confidence level of 95%. The
results of the Tukey procedure are given below. ("lower" is the lower bound of the
interval, "upper" is the upper bound.)
How many of these pairwise differences are statistically significant? (No calculations
required!)
