Which of the following tools would be most appropriate for collecting data to
study the symptoms of a problem?
Check sheet
The most important aspect of functional requirements is that they
Be traceable to the voice of the customer
Which of the following control charts is most appropriate for monitoring the
number of defects on different sample sizes?
U
A u-chart is an attributes control chart used with data collected in subgroups of
varying sizes. U-charts show how the process, measured by the number of
nonconformities per item or group of items, changes over time.
Which of the following is most important in evaluating and understanding design
intent?
Identifying the functional requirement
If a process follows an exponential distribution with a mean of 25, what is the
standard deviation of the process?
25
It can be shown for the exponential distribution that the mean is equal to the
standard deviation; i.e., μ = σ = 1/λ
Which of the following activities is value-added?
Process
, A black belt plans to test the performance of workers before and after training,
which of the following hypothesis tests should be used to determine whether the
training actually improved the workers' performance?
Paired t test
A paired t test (also called a correlated pairs t-test, a paired samples t test or
dependent samples t test) is where you run a t test on dependent samples.
Dependent samples are essentially connected — they are tests on the same
person or thing. For example:
Knee MRI costs at two different hospitals,
Two tests on the same person before and after training,
Two blood pressure measurements on the same person using different
equipment.
The purpose of using control charts is to
Evaluate process performance over time
The control chart is a graph used to study how a process changes over time. Data
are plotted in time order. A control chart always has a central line for the average,
an upper line for the upper control limit, and a lower line for the lower control
limit. These lines are determined from historical data.
Data being used in the initial set-up of a process are assumed to have a normal
distribution. If the normal (target) is set at the center of the distribution, and the
specification limits are set at ±3 σ. From the center, then the Cpk is equal to
1.00
Which of the following is defined as continuous, incremental improvement?
Kaizen
Which of the following performance measures is most appropriate for evaluating
the tangible effects of a six sigma project?
Cycle time
Which of the following is the best way to enhance the long term availability of a
machine?
Total productive maintenance
Typically, which of the following activities is done earliest in the formation of a
project team?
Identify the objective
A black belt is developing a failure mode and effects analysis (FMEA) for the
hamburger preparation station in a fast-food restaurant. The following ratings
were developed for the low-heat temperature failure mode.
Severity = 9, Occurrence = 2, Detection = 1
What is the risk priority number for this FMEA?
18
Which of the following statements is true about the theory of constraints?
Most constraints are the result of policies
