Each of the items listed would impact the Process Capability for a process with a continuous output except ___________________.
Range Charts are the technique used to determine if Special Causes are occurring within the subgroups of the ______________.
When a Belt properly analyzes the results of an experiment he must examine the Residuals in expectation of finding all of the following except _________.
A(n) ______________ is best used to compare a Machine 1 average quality characteristic to the same quality characteristic of Machine 2.
What is the Ppk of a process with a spread of 24 units, an average of 68, an upper limit of 82 and a lower limit of 54?
A(n) ______________ is best used to compare a Machine 1 average quality characteristic to the same quality characteristic of Machine 2.
Appropriate measures means that measurements are ______________.
When conducting a Hypothesis Test using Continuous Data the proper sample size is influenced only by the extent to which we need to assess a Difference to be detected but not the inherent variation in the process.
Common and ______________ Cause Variation are the focus of Statistical Process Control.
Which Experimental Design typically is most associated with the fewest number of input variables or factors in the design?
Screening experiments are the proper choice when a Belt is faced with the situation of highly Fractional Factorial Designs.
When variation is removed from the output of a process then the process customer can have more confidence in the experience that results from the process.
Of the various types of data shown which is NOT representative of Variable Data.
If the production is for higher volume and monitoring and the Mean and variability is to be monitored for four machines producing product and the characteristic to be monitored is Variable Data, which SPC Chart is best to be selected?
When a Belt implements an improvement that is automated thus requiring no particular understanding for use he has applied which Lean tool?
Kaizens or Kaikakus and Six Sigma projects are intended to create incremental process improvements versus breakthrough, significant improvements.
A Belt working in a supply chain environment has to make a decision to change suppliers of critical raw materials for a new product upgrade. The purchasing manager is depending on the Belt’s effort requiring that the average cost of an internal critical raw material component be less than or equal to $4,200 in order to stay within budget. Using a sample of 35 first article components, a Mean of the new product upgrade price of $4,060, and a Standard Deviation of $98 was estimated. Select the answer that best states the Practical Problem.
The relationship between a response variable and one or more independent variables is investigated and modeled by use of which of these?
Which one of these tools is frequently used to help drill down to possible causes once a Fishbone Diagram is constructed?
Which statement(s) are correct about the Pareto Chart shown here for the DOE analysis? (Note: There are 2 correct answers).
