Question:

Use the averages for the six saws A-F

\[
2.122,2.060,1.975,2.070,2.156,1.920
\]

to compute the brand sum of squares on two degrees of freedom, the saw replicate sum of squares on three degrees of freedom, and the $F$-ratio (ratio of mean squares). Why is this two-part decomposition structurally different from the threepart decomposition in the preceding exercise?
