Chapter 12, Problem 15P

A research study comparing three treatment conditions produces $T=\text{2}0$ with $a=\text{4}$ for the first treatment. $T=\text{1}0$ with $a=\text{5}$ for the second treatment, and $T=\text{3}0$ with $a=\text{6}$ for the third treatment. Calculate $S{S}_{\text{between treatments}}$ for these data.
