, Chapter: 8 -Problem: 41 >> Suppose that three of the parts produced by the process in Exercise 8.39 are assembled into a product that has upper and lower specifications at 624 and 630 units, respectively. What is the ppm defective of the assemblies? What actions would you recommend to improve the performance of the assembled product?
Answer Preview: PPM is arrived at by simply taking the number of defective units in a same size, dividing that number by the total sample size, and multiplying by 1 m…

Answer Preview: After anal…

, Chapter: 13 -Problem: 21 >> In an unreplicated design, the number of degrees of freedom associated with the “pure error” component of error are zero.True  False
Answer Preview: Since, It is given that the design is unreplicated, t…

, Chapter: 2 -Problem: 2 >> What role does risk play in project selection and the Define step of DMAIC?
Answer Preview: Common risks in project selection include a focus on projects driven by current problems (not based on strategic business objectives), project scope (too large) and business impact (too narrow). In the Define step of the DMAIC process, anticipating risks such as resource availability, schedule restrictions, technology limitations, organizational readiness (and culture), and other factors allows for pro-active planning and escalation (if needed). Your answer could differ based on your experience. You should recognize that risks can arise from many sources and may have varying impacts on project …

, Chapter: 8 -Problem: 40 >> Suppose that four of the parts produced by the process in Exercise 8.38 are assembled into a product that has upper and lower specifications at 795 and 805 units, respectively. What is the ppm defective of the assemblies? What would you recommend to improve the performance of the assembled product?
Answer Preview: Consider the manufacture of a simple product (X) resulting from the assembly of three (3) parts type …

, Chapter: 1 -Problem: 13 >> What would motivate a business to compete for the Malcolm Baldrige National Quality Award?
Answer Preview: While the Malcolm Baldrige National Quality Award recognizes national role model practices across mu…

, Chapter: 13 -Problem: 23 >> Adding center runs to a 2k design affects the estimate of the intercept term but not the estimates of any other factor effects.True  False
Answer Preview: TRUE This is very important fundamental material and experimental design be…

, Chapter: 14 -Problem: 16 >> The coordinates of the points on the path of steepest ascent are proportional to the effect estimates from the first-order model.True  False
Answer Preview: My answer is true, because t…

, Chapter: 13 -Problem: 14 >> An interaction effect in the model from a factorial experiment involving quantitative factors is a way of incorporating curvature into the response surface model representation of the results.True  False
Answer Preview: True Suppose that .coe add an intuaction term to the model Y= …

, Chapter: 13 -Problem: 15 >> If an interaction effect in a factorial experiment is significant, the main effects of the factors involved in that interaction are difficult to interpret individually. True  False
Answer Preview: When we have interaction effects that are statistically signi…

, Chapter: 13 -Problem: 22 >> In a replicated 23 design (16 runs), the estimate of the model intercept is equal to one-half of the total of all 16 runs.True  False
Answer Preview: replicated 23 design (16 runs), There are 32 treatments and abcdef …

, Chapter: 1 -Problem: 9 >> Who was Walter A. Shewhart?
Answer Preview: Walter A. Shewhart is often called the father of modern quality contr…

, Chapter: 13 -Problem: 16 >> Consider the following incomplete ANOVA table: a. Complete the ANOVA calculations. b. Provide an interpretation of this experiment. c. The pure error estimate of the standard deviation of the sample observations is 1. True? False Transcribed Image Text: Source A B AB Error Total SS ? 80.00 30.00 ?
