Question
A quality control director at a clothing company has set up a 2^2 design of experiment (DOE) to determine if operator, machine type, or an interaction of operator and machine type affect the breaking strength of wool (in psi).
Questions are based on the following: A quality control director at a clothing company has set up a 2^2 design of experiment (DOE) to determine if operator, machine type, or an interaction of operator and machine type affect the breaking strength of wool (in psi). The data and Excel output are shown below: What is the main effect of machine type? Using alpha =.05, develop a DOE model. What is the predicted breaking strength for wool processed on Machine 2 by Operator A?Explanation / Answer
6) Interpret this excel result as "
Sample factor for variance Operator, whose effect is significant given a P value < 0.05
Column factor for Machine type , whose effect is significant given a P value < 0.05
The 3rd source fo variation "Interaction" is > 0.05 which is not significant, meaning the combo effect is not significant
Therefore Machine type does have significant effect on the wool' breaking.
