Refer to Scenario A: Suppose the company wants to improve its capability to a 5-sigma level by reducing the variability of its process. Which of the following standard deviations would meet a 5-sigma capablity for Cpk? Check all that apply, and assume the process mean remains unchanged from the original problem. .005 .015 .025 .035 .045 .055 Following the previous question, we can conclude the process is out of control. Which of the following appear in the control charts that would lead to this conclusion? Check all that apply. R chart: Data exceed the UCL/LCL range. R chart: Systematic oscillation R chart: Consecutive points above/below the CL R chart: Consecutive increase/decrease in readings X-bar chart: Data exceed the UCL/LCL range. X-bar chart: Consecutive points above/below the CL X-bar chart: Consecutive increase/decrease in readings Refer to Scenario A: Suppose the company wants to improve its capability to a 5-sigma level by reducing the variability of its process.
