(Use SST = 1709.836) (d) Using alpha = 5%, test to determine whether there is any significant effect on vibration due to (i) Bit size (ii) Speed (iii) Interaction between bit size and speed (e) Write down the fitted regression model. 2 2. An experiment was performed to investigate the surface finish of a metal part. The experiment is a 2 3 factorial design in the factors feed rate (A), depth of cut (B), and tool angle (C). The observed surfacefinish data for this experiment are presented in the following table: Treatment A B C Surface Finish  +   + + +   + +  + + + + + + 9, 7 10, 12 9, 11 12, 15 11, 10 10, 13 10, 8 16, 14 (a) Compute the factor effects and sum of squares associated with the effects. 3 (b) Construct the ANOVA table. (Use SST = 92.9375) (c) Which effects have significant impact on the surfacefinish? (use alpha = 0.05) 4...
