Exam 19: Statistical Applications in Quality Management

SCENARIO 19-4 She also decides that lower and upper specification limit for the critical-to-quality variable should be 10 and 30 seconds, respectively. -Referring to Scenario 19-4, suppose the sample mean and range data were based on 6 Observations per hour instead of 5.How would this change affect the lower and upper control Limits of an R chart?

Variation signaled by individual fluctuations or patterns in the data is called

True or False: Total Productive Maintenance focuses on preventing the causes of defects.

True or False: The SS method establishes ways to eliminate unnecessary housekeeping aspects of a work environment.

True or False: A process capability is estimated by the percentage of product or service that fall outside the specification limits.

The principal focus of the control chart is the attempt to separate special or assignable causes of Variation from common causes of variation.Which causes of variation can be reduced only by Changing the system?

True or False: A master black belt is among the tools of Lean Six Sigma.

SCENARIO 19-1 -Referring to Scenario 19-1, what is the numerical value of the center line for the p chart?

True or False: Mistake Proofing devices focus on methods that enable participants to reduce setup time for equipment and resources and materials needed for changeover.

SCENARIO 19-4 She also decides that lower and upper specification limit for the critical-to-quality variable should be 10 and 30 seconds, respectively. -Referring to Scenario 19-4, suppose the supervisor constructs an R chart to see if the variability in Collection times is in-control.This R chart is characterized by which of the following?

SCENARIO 19-1 -Referring to Scenario 19-1, what is the numerical value of the upper control limit for the p chart?

Which of the following is a method for breaking process into a series of steps in order to Eliminate defects and produce near perfect results?

True or False: The purpose of a control chart is to eliminate common cause variation.

True or False: Quick Changeover Techniques establish ways to eliminate unnecessary housekeeping aspects of a work environment.

True or False: The focus of Lean Six Sigma is on removing non-value added steps and waste which can exist in any part of an organization.

True or False: Quick Changeover Techniques establish ways to clean and maintain the necessary housekeeping aspects of a work environment.

True or False: SS method is among the tools of Lean Six Sigma.

True or False: The CPL and CPU indexes are used to measure process' actual performance rather than its potential.

SCENARIO 19-3 -Referring to Scenario 19-3, suppose the analyst constructs an R chart to see if the variability in Production times is in-control.What is the upper control limit for this R chart?

SCENARIO 19-3 -Referring to Scenario 19-3, suppose the analyst constructs an chart to see if the production Process is in-control.Which expression best describes this chart?
