The process improvement technique that sorts the vital few from the trivial many. correct
answers Pareto Analysis
A fishbone chart is also known as a correct answers cause and effect diagram
When sample measurements falls inside the control limits, it means that: correct answers if
there is no other pattern in the samples, the process is in control
Pareto charts are used to correct answers organize errors, problems, or defects
If x-bar bar= 23 ounces, σ = 0.4 ounces, and n = 16, what will be the ±3σ control limits for
the x-bar chart? correct answers σ= .4/Square root 16
= .1
23 +- 3(.1)
23.3 and 22.7
To set x-bar chart upper and lower control limits, one must know the process central line,
which is the:
A) average of the sample means.
B) total number of defects in the population.
C) percent defects in the population.
D) size of the population.
E) average range. correct answers average of the sample means
which of the following is true regarding the process capability index Cpk? correct answers
The larger the Cpk, the more units meet
A manager wishes to build a 3-sigma range chart for a process. The sample size is five, the
mean of sample means is 16.01, and the average range is 5.3. From Table S6.1, the
appropriate value of D3 is 0, and D4 is 2.115. What are the UCL and LCL, respectively, for
this range chart? correct answers LCL=0(5.3)
=0
UCL=2.115(5.3)
=11.2095
round to 11
assignable variation correct answers is to be identified and investigated
break even is the number of units at which? correct answers total revenue equals total cost
A product focused process is commonly used to produce? correct answers high volume and
low variety produces
For a 3-sigma x-bar chart where the process standard deviation is known, the upper control
limit:
A) is 3σ below the mean of sample means for a 3σ control chart.
