2. 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: Drying Time (min) Paint 20 25 30 1 74 73 78 64 61 85 50 44 92 92 98 66 86 73 45 68 88 85 a. State the hypotheses of interest in this experiment. b. Test the above hypotheses and draw conclusions using the analysis of variance with a = 0.05. 2.
