sum of squares error and treatment

I have information on 7 treatments, x,  and am assessing their effects. If I have the means and standard deviations of the outcome measurement, y, along with the numbers of observations for each treatment, n, how can I calculate the sum of squares for the error and for the treatment effects?

I would run the data through PROC GLM.

I do not have the data; this is an unusual scenario.

Then you find the ANOVA formulae in some text book (or at Wikipedia) and plug in your means and standard deviations into the formulae.
