Assume that 100 subjects received one of four treatment combinations and produced the data reported below. Conduct a two-factor ANOVA and complete an ANOVA table reporting the relevant SS, df, MS, F's.

N=100 n=25

the table shows A1 and A2 at the top and B1 and B2 on the side. Under A1 it shows the means : 100 and 40 goind down. Next to that is the variance 900 and 800 going down. Then for A2 the mean is 70 and 60 and the variance is 700 and 1200.

I am having trouble finding the s2 Total. I do not know what to do.
