QUESTION 7. Describe the two phases of control chart operation.

QUESTION 8. What are two guidelines for the selection of sample size in an attribute control chart sampling plan? Write the equations corresponding to these guidelines.

QUESTION 1. Per Deming, statistical process control is the responsibility of: a) Management b) Process operators c) Process owners only d) Design engineers QUESTION 2. Engineering ethics consists of three components: awareness of project phases, accountability for consequences of a projects design, and autonomy required to make engineering judgments. The DMAIC approach may engender awareness because: a) Quality engineers must take a narrow focus on the quality characteristic directly under their control b) Process engineers select an optimized producer's risk for the input quality of the present process c) Process engineers use control charts to assess the presence or absence of an assignable cause d) Quality engineers must be knowledgeable of all phases of a project when implementing DMAIC QUESTION 3. Quality is a) The number of defects in a process output b) Inversely proportional to variability c) Not a competitive weapon d) Too costly to be rigorously applied in most processes QUESTION 4. Which of the following parameters are statistical characteristics of the process? a) Natural tolerance b) Specification band c) Process target
