Q2. An engineer, suspecting that the surface finish of metal parts is affected by both the type of paint utilized and the duration of drying time, conducted tests using two types of paint and three drying times (20, 25, and 30 minutes). Each combination of paint type and drying time was tested on three parts, yielding the following data: Drying Time (min) Paint 201 25 30 1 74 73 78 64 61 85 50 44 92 2 92 98 66 86 73 45 68 88 85 (a) State and test the appropriate hypotheses using the analysis of variance with a =0.05. Use the formulations to find SS, MSE, and F values. (b) Analyze the residuals from this experiment. Put Computer outputs. Graphs and ANOVA table. Q2.
