An example of assignable variation in a production system may be that workers are not identically trained.

Question 41

The capability index is used to gauge economic changes in service systems.

Question 42

A "p chart" has upper and lower control limits expressed as lines on the chart.As long as the sample values fall between these two lines there is no need to investigate process behavior.

Question 43

An example of assignable variation in a production system may be that a machine is not adjusted properly.

Question 44

It is impossible to have zero variability in production processes.

Question 45

Measurement by attributes means taking a sample,measuring the attribute in question and determining the level of quality in the population from which the sample was drawn.

Question 46

Process control is concerned with monitoring quality after the product or service has been produced.

Question 47

If the fraction defective is 0.12 based on a sample size of 16,the standard deviation used in the "p" chart is about 0.08.
