An engineer suspects that the surface finish of metal parts is influenced by the type of paint used and the drying time. He selected three drying times-20, 25, and 30 minutes—and used two types of paint Three parts are tested with each combination of paint type and drying time. The data are as follows: (a) State the hypotheses of interest in this experiment. (b) Test the hypotheses in part (a) and draw conclusions using the analysis of variance with a = 0.05. (c) Analyze the residuals from this experiment. of variance with a = 0.05. (b) Graphically analyze the interaction. (c) Analyze the residuals from this experiment
