A chemical engineer is interested in how polymethyl methacrylate (PMMA) particles can be prepared by dispersion polymerization in the presence of a stabilizer polyvinyl pyrrolidone (PVP). DS 11.1.5 gives the average particle diameters achieved in various experiments with three different amounts of the stabilizer. How does the amount of stabilizer affect the average particle diameter? Use a computer package to obtain a graphical presentation of the data set an analysis of variance table, and pairwise comparisons between the different stabilizer levels.
