In which order will you remove the statistically insignificant terms? AC, AB, ABC ABC, AB, AC AB, ABC, AC AB, AC, ABC3. Five meat softeners are to be tested in a cooking experiment to be completed in a short time. Five different heat settings and five different chefs are considered as noise factors. Which of the following is the most effective tool to be used in this case? Randomized Design Non Randomized Design Randomized Design with Center Point Latin Square Design4. Which of the following is NOT a deliverable of Improve Phase?

A factor 5 design with 8 runs is a ____________ Resolution IV design Resolution III design Resolution V design Resolution VI design6. What is the number of replications required to run a full factorial design with a power of 90%, if there are 3 factors and 2 levels? Assume the difference to be detected is 0.5 and standard deviation is 0.25 1 2 3 47. The figure below shows the interaction plot indicating the impact of Speed of Service and Quality on the outcome “Satisfaction”. What can be said about the interaction between the two inputs? a) There is interaction between the two inputs - Speed of Service and Quality b) There is no interaction between the two inputs - Speed of Service and Quality c) There is interaction between the input variable - Speed of Service - and the output variable - Satisfaction d) There is interaction between input variable - Quality - and the output variable - Satisfaction8. Which of the following is an advantage of running a pilot? It can help test the solution You don’t need to do full scale implementation if you run a pilot You can handover the process to the process owner if the pilot is successful None of the above9.
