⊚ false
12) The development of acceptance sampling is attributed to the works of Taguchi and Ishikawa.
⊚ true
⊚ false
13) An in-control process will always exhibit some common cause variation.
⊚ true
⊚ false
14) Common cause variation does not indicate an out-of-control process.
⊚ true
⊚ false
15) The presence of common cause variation is an indication that the process is out of control.

16) Special cause variation exists when the process produces observations that are not from the
same population as the majority of the observations.
⊚ true
⊚ false
17) Control charts are used to monitor the quality of a product before it is produced.
⊚ true
⊚ false
18) A process may be in a state of control even if one sample mean is more than two standard
deviations above the centerline.
⊚ true
⊚ false
19) A p-chart is a type of process control chart that can be used for plotting the proportion of
nonconforming sampled items.
⊚ true
⊚ false
20) The Cpk index may indicate a capable process even though the Cp index is unacceptable.
⊚ true
⊚ false
21) A moving range (MR) chart is appropriate to monitor variation when every single item is
being inspected (n = 1) since the range (R) cannot be calculated.
⊚ true
⊚ false
22) If a single sample mean is 2.1 standard deviations above the centerline, the process is not in
control.
