Question:

For two studies, each comparing three groups, the box plots below show results. (Each box plot is based on a random sample of size 40.)
a. Judging from the box plots, which study will more likely lead to a rejection of the ANOVA null hypothesis of equal population means? Explain.
b. Which study will have the large value for the F test statistic? Why?
c. The P-value for the ANOVA F test for the second study equals 0.001. Does this necessarily imply that all three population means are different from each other?
