The Quality Group studied of a plant that produces a high-volume, blow-molded container. The quality manager at the plant wants to lower the average thickness for t expensive layer of material and still meet specifications. Specification limits for individual thickness values are .10 to .30 millimeter. Refer the file BLWMLD.xlsx to answer the following questions: • Find the standard deviation of the process data. • Calculate the capability index, Cp, for the process and interpret the result. Compare the LCL of the process with the LSL. Does this imply that the average thickness of the material can be lowered and still meet specifications?

Question
Transcribed Image Text:The Quality Group studied of a plant that produces a high-volume, blow-molded
container. The quality manager at the plant wants to lower the average thickness for the
expensive layer of material and still meet specifications. Specification limits for
individual thickness values are .10 to .30 millimeter. Refer the file BLWMLD.xlsx to
answer the following questions:
• Find the standard deviation of the process data.
• Calculate the capability index, Cp, for the process and interpret the result. Compare
the LCL of the process with the LSL. Does this imply that the average thickness of the
material can be lowered and still meet specifications?
