Consider a two-way analysis of variance experiment with treatment factors A and B,with factor A having four levels and factor B having three levels.The results are summarized below.
$$\begin{array} { l r r }
\text { Source of Variation } & d f & \text { SS } \
\text { Factor A } & & 71 \
\text { Factor B } & &63 \
\text { Interaction } && 50 \
\text { Error } & &280 \
\text { Total } &71 & 464
\end{array}$$
Compute the mean squares and appropriate F statistic to test the null hypotheses of no effect from either factor at α = .05 (assumption: no interaction effect).
