 0.0850
 0.0401
 0.42
 0.0495

Why do we need Control Plan? Answer is/are?

 It helps new people to understand the Process and its Control Steps.
 All the Options.
 It helps to produce Consistent and Predictable Quality.
 It communicates what do we have to Check and Control throughout the Process.

In a mature Six Sigma program?

 There is not much left to be gained by Six Sigma Projects
 The Quality & HR Department is the key Customer contact.
 Nearly everyone in the organization is involved in some way at some time
 Only a small percentage of the employees are involved, and only for limited times.

 Pareto Chart
 Run Chart
 Control Chart
 Scatter Diagram

Evaluating Customer Complaints allows an organization to?

 Exercise recovery skills to win back Customers loyalty
 Prevent Problems
 Focus on all the issues that cause problems
 None of the Options.

To Break down a large project into smaller, more manageable projects, a black belt should use?

 An Analytical Hierarchy diagram
 A Work Breakdown Structure

 A Flow Chart

What is the relationship between Bias & Linearity?

 Bias is the Measure of inaccuracy at a point. Linearity is an evaluation of the Bias at several Poin
 Both options (A) & (B)
 None of the Options.
 Linearity is a special case of Bias

A Firm manufactures a certain industrial component that has a length which is approximately normally distributed, with the Mean equal to 800 and a Standard Deviation of 40. Test the Hypothesis (H0 : Mean=800 vs. H1 : Mean≠800) if a Random Sample of 20 Parts has an Average length of 788. ά is 10 %.

 None of the Options
 H0 is 800 is Correct
 H1 is Correct

The Kano Model is interpreted as Follows?

 Customer Wants, Needs, and Expectations are dynamic and must be monitored continuously. Providing Products or Services that match the Customer’s Expectations is not enough to assure Customer Satisfaction.
 Customer Satisfaction is determined solely by the quantity of the Product or Service delivered
 Customers will be satisfied if you supply them with Products and Services that meet their needs at a fair price.
 Customer wants can be determined once and for all and used to design high-quality Products and Services.

The Central Limit Theorem states that the distribution of Sample Means approximates a Normal Distribution if;

 The Sample Size is sufficiently Large.
 The Sample is Normally Distributed
 The Sample is randomly Selected
 The Population is Normally Distributed

In a Process FMEA, Process and/or Design changes can?

 Increase the Probability of Detection.
 All the Options.
 Reduce the Probability of Occurrence
 Reduce the Severity Raking.

 Equates to a Capability Index of 1.33
 Provides half the Defects of a 3 Sigma Level of Quality.
 Implies 99.73% of the output will meet Customer Requirements.
 Represents 3.4 Defects per Million Opportunities

Failure Mode & Effect Analysis involves what activity?

 The determination of the probability of failure in a specified period of time
 A study of the probability of success in a given time period
 The expected number of failure in a given time interval
 The study of how a product fails and what causes the failure

In general, if %GRR is Greater than 30%, the Measurement System is considered?
