131. Consider that for a particular process, the p has shifted to .4 and the process has gone out of control. The corresponding value of beta is found to be .3356. The value of Average Run Length is:

  1. 2.5
  2. 1.5 ((1/1-beta) provides us with average run length)
  3. 1.0
  4. 2.7
Correct answer: (B)
1.5 ((1/1-beta) provides us with average run length)

132. Consider for a process in control, the value of alpha is .0015. What is the value of the average run length?

  1. 666 ( 1/alpha gives us an estimate of average run length)
  2. 555
  3. 444
  4. None of the above
Correct answer: (A)
666 ( 1/alpha gives us an estimate of average run length)

133. Identify the charts which might give an indication of process going out of control (before the process has actually changed)

  1. X bar and c
  2. P and c
  3. R and u
  4. X bar and R
Correct answer: (D)
X bar and R

134. The four phases of the Shewart cycle are:

Correct answer: (C)
Plan, Do, Act, Check

135. For a process which is six sigma complaint, the percentage of products within specifications is:

  1. 95.20%
  2. 99.73%
  3. 99.10%
  4. 96.78%
Correct answer: (B)

  2. Identify Design Attributes / Requirements
  3. Conduct an Evaluation of Competing Products.
  4. Evaluate Design Attributes and Develop Targets
Correct answer: (A)
Identify Customer Attributes

138. For a double sampling plan the probability of acceptance on the combined samples is calculated as:

  1. Maximum of probability of acceptance of first and second sample
  2. Product of probability of acceptance of first and second sample
  3. Average of probability of acceptance of first and second sample
  4. Sum of probability of acceptance of first and second sample
Correct answer: (D)
Sum of probability of acceptance of first and second sample

139. ______________ can be defined as small subset of a lot.

  1. Defect
  2. Fraction Acceptable
  3. Sample
  4. Acceptance Number
Correct answer: (C)
Sample
