A company conducts an experiment to analyze the effect it has on the finish of a metal part. Factors to consider are: The depth of cut and the feed rate of the manufacturing machine.Three replicates of each treatment are carried out.The finish is measured in grams and it is desired to find the optimal conditions that will minimize the grams that are worn on the finish.A) Perform ANOVA analysis to determine which elements of the two-factor factorial design model are significant.B) Using the main effects and interaction plots, determine the optimal conditions for the target response variable.
