Question 1

To measure the voltage of batteries,one would sample by attributes.

Accepted Answer

A) True 
 B)False

Question 2

The process capability measures Cp and Cpk differ because:

Accepted Answer

A) only one ensures the process mean is centered within the limits. 
B) Cp values above 1 indicate a capable process,while Cpk values above 2 indicate a capable process. 
C) They do not differ: both are identical. 
D) Cp values for a given process will always be greater than or equal to Cpk values. 
E) Both A and D are correct.

B) .081 
C) 8.1 
D) .0273 
E) .0863

Question 4

A local manufacturer supplies you with parts,and you would like to install a quality monitoring system at his factory for these parts.Historically,the defect rate for these parts has been 1.25 percent (You've observed this from your acceptance sampling procedures,which you would like to discontinue).Develop ± 3σ control limits for this process.Assume the sample size will be 200 items.

Accepted Answer

p-bar is 0.0125; the standard error of t
