The commercial value of softwood species would be increased if the wood could be treated to meet preserver's standards. The response, \(y\), is the amount of retention \(\left(\mathrm{lb} / \mathrm{ft}^{3}\right)\) of the preservative. Two treatments (preservatives) were considered and the samples were either incised or unincised. Further, the conditions of spruce trees were not defoliated, partially defoliated, or totally defoliated.

Perform an appropriate analysis of variance and interpret the results.
