The removal of ammoniacal nitrogen is an important aspect of treatment of leachate at landfill sites. The rate of removal (in percent per day) is recorded for several days for each of several treatment methods. The results are presented in the following table. (Based on the article "Removal of Ammoniacal Nitrogen from Landfill Leachate by Irrigation onto Vegetated Treatment Planes," S. Tyrrel, P. Leeds-Harrison, and K. Harrison, Water Research, 2002:291–299.) Treatment Rate of Removal 5.21 4.65 5.59 2.69 7.57 5.16 6.24 5.94 6.41 6.85 9.18 4.94 4.04 3.29 4.52 3.75 Construct an ANOVA table. You may give a range for the P-value. Can you conclude that the treatment methods differ in their rates of removal? a. b. ABCAE
