Essay

An experiment was designed to investigate the effectiveness of 5 different methods that are used for decontaminating topsoil. Each of the 5 methods is applied to a plot of contaminated soil at 3 different Superfund sites (blocks) and the reduction in heavy metals in the topsoil is recorded. The experiment yields the following summary information. SSTo = 1,209.3 SSTr = 635.8 SSBl = 297.6 ​
a) Construct the ANOVA table for this experiment.
b) Test for the null hypothesis that there is no difference in the mean reduction of heavy metals for the 5 different methods using a .05 significance level.
