Factorial Design (DOE)

An engineer is interested in the effects of cutting speed (A), tool geometry (B), and cutting angle (C) on the life (in hours) of a machine tool. Two levels of each factor are chosen, and three replicates of a 23 factorial design are run. The results show the averages of the three replicates

A	B	C	Mean
-	-	-	26.00
+	-	-	34.67
-	+	-	39.67
+	+	-	49.33
-	-	+	42.33
+	-	+	37.67
-	+	+	54.67
+	+	+	42.33

Estimate the factor effects. (Please show steps)
Which effects appear to be large?

A 22 factorial design was used to investigate the effects of stearate concentration and mixing time on the hardness of a tablet formulation. The results are presented in the attached table (Hardness vs time and stearate.mtw). Calculate the regression equation and present the ANOVA table. Test the main effects and interaction effect (ab) for significance. Graph the data and comment on whether or not the plots indicate the possible interaction between the effects or the mixing time and stearate concentration...

An industrial engineer employed by a beverage bottler is interested in the effects of two different types of 32-ounces bottles vs the potential fatigue differences resulted from delivering 12-bottle cases of the product. The two bottle types are glass and plastic. Two workers are used to perform the task that consists of moving 40 cases of the product 50 feet on a standard type of hand truck and then, stacking the cases in a display. As a measured of the...
