Problem regarding the treatment combinations

Reference no: EM131015102

A second experiment on the lens coating discussed in Problem 1 was run to study the effects of both the pH level and the catalyst level on the adhesion. Three levels of pH were studied along with two levels of catalyst. Five mea surements were taken for each of the treatment combinations. The data for the experiment are stored in adhesion2 .txt.

(a) Make plots of the data, including an interaction plot.

(b) Write a paragraph summarizing the results of this experiment.
