The sums of squares due to the polynomial terms in the analysis of the 1981 data were not partitions of the analysis of variance due to the fact that a given pollutant treatment was not constant over the levels of the other pollutant and the two replications. Rerun the polynomial analysis using the mean ozone level for each ozone treatment and the mean sulfur dioxide level for each sulfur dioxide treatment; that is, use

_i··1
and

_·j·2. How does this change your results? What polynomial model do you adopt? Are the sums of squares due to the polynomial terms in ozone level partitions of the ozone treatment sum of squares? Are the sequential sums of squares due to the polynomial terms in sulfur dioxide level partitions of the sulfur dioxide treatment sum of squares?
