# Show that $\pmb{\hat{\beta}}$ and $\pmb{\hat{\sigma^2}}$ are independents and $SSRes$ and $SSR$ are independents too

I can't show that $$\pmb{\hat{\beta}}$$ and $$\pmb{\hat{\sigma^2}}$$ are independents and that $$SSRes$$ (residuals) and $$SSR$$ (regression) are independents too.

I need to show this in matrix notation.
