1. 1. Review the section "Statistical Process Control Defined." Explain how environment and the Five M's can affect processes used in the following:
      1. A hardware store
      2. A hospital
      3. An accounting firm
      4. A newspaper
      5. A factory
      6. A new car dealership
   2. Explain the relationship that exists between the histogram and the control chart.
   3. Contrast the histogram's characteristic of representing a "snapshot" of a process with a control chart.
   4. Defend the statement that the operator of the process should be the owner and data plotter of the control chart, as opposed to a person from quality assurance or engineering, for example.
   5. Comment on the significance of this statement: "Control chart parameters must be statistically derived and cannot simply be specifications or some arbitrary values that are based on production expectations."
