(c) Write out expressions for all sums of squares (in terms of the temperatures yijk m , using the dot-and-bar notation), including the (corrected) total sum of squares and error sum of squares. Also specify their corresponding degrees of freedom. (d) For each term in the model (except the overall mean and error), use the rules to nd an F -statistic for testing whether the term is present, assuming an unrestricted model. Do any of your answers change if you assume a restricted model instead?
