Assume that a total of 75 subjects were tested in a balanced two-way fixed-effects factorial experiment. A plot of the means from the study is shown next. The dependent variable is Y, and the factors are A and B.

a. Give the left two columns (the source and degrees-of-freedom columns) of the ANOVA table for the data plotted.
b. Assume that the plot shows the population means. Indicate which significance tests should hopefully yield significant results in the ANOVA table.
