What are Assignable variations?
Skill/Topic: Statistical Process ControlA) Assignable variations are caused by factors that can be clearly identified and possibly managed
-
What are common Variations?
Skill/Topic: Statistical Process ControlA) Common variations are those variations that are inherent in the system itself
-
What is Precision of Measurement?
Skill/Topic: Statistical Process ControlA) If the average of all measurements falls relatively close to an understood point (on target), then the process is said to be accurate.
-
What are Data Sets?
Skill/Topic: Quality ProcessA) The numbers from measurements that represent a parameter in common is called a Data Set
-
When do we use a np chart?
Skill/Topic: Statistical Process ControlA) The np Chart can be used for the special case when the subgroups for constructing an attribute chart are of equal size.

LSL is the highest level considered to be acceptable
Skill/Topic: Statistical Process ControlA) TrueB) False
-
Armand V. Feigenbaum developed the concept of Total Quality Control

How many parameters are there in BETA Distribution?
Skill/Topic: Statistical Process ControlA) 1B) 2C) 3D) 4Explanation: BETA Distribution has four parameters: a and b, which are, respectively, the minimum and maximum values that a beta random variable can assume, and g and h, which are the shape parameters.

Who is the Customer of a Process?
Skill/Topic: Quality ProcessA) In Process Improvement, we define the customer as ‘the next person in line’ – whoever receives the output or value of the product or service.
-
The Bell-Shaped curved is also an example of a ___________ distribution
Skill/Topic: Statistical Process ControlA) SymmetricB) Asymmetric
-
The specification limits for the inside diameter of a hole are (0.995", 1.005"). The standard deviation of the inside diameters generated by a lathe machine selected to process this component is estimated to be 0.002". Compute the Cp index of this process. Assume that the inside diameters generated by the machine follow normal distribution
Skill/Topic: Statistical Process ControlA) 0.7444B) 0.8333C) 0.9673D) 0.8777Explanation: Cp = (USL-LCL)/ 6σ = 1.005 - 0.995 / (6 * 0.002 )= 0.8333
-
Process Capability Ratio PCR or Cp = ------------------------------
Skill/Topic: Statistical Process ControlA) Cp = (USL-LCL)/ 6σExplanation: In this formula, USL and LSL are the upper and lower specification limits of the quality characteristic, respectively. The quantity in the denominator, 6σ signifiesthe fact that 99.73% of the values generated by the process is contained within
