The article “Influence of Supplemental Acetate on Bioremediation for Dissolved Polycyclic Aromatic Hydrocarbons” (T. Ebihara and P. Bishop, Journal of Environmental Engineering, 2002:505–513) describes experiments in which water containing dissolved polyaromatic hydrocarbons (PAH) was fed into sand columns. PAH concentrations were measured at various depths after 25, 45, and 90 days. Assume that three independent measurements were made at each depth at each time. The data presented in the following table are naphthalene concentrations (in mg/L) that are consistent with means and standard deviations reported in the article.
a. Construct an ANOVA table. You may give ranges for the P-values.
b. Perform a test to determine whether the additive model is plausible. Provide the value of the test statistic and the P-value.
