ANOVA and the F distribution

Main Question or Discussion Point

Hello all,

Does anyone know where I could find a formal proof that

$$\frac{\text{MS between}}{\text{MS within}}$$

has a F distribution under the null in ANOVA?

Wikipedia states that the ratio of two chi-square random variables is F. If each MS term is normal then their sum will be Chi-squared.
