Q2. The Pareto Principle is a technique used by quality managers to determine which quality control problems concerning a particular service or manufacturing process should be corrected. Which of the following statements best represents the philosophy employed by this principle?

1. The majority of defects are caused by a small percentage of the identifiable problems. Improvement efforts should be reserved for those few vital problems
2. A and D
3. In order to achieve zero defects, all quality control problems, including those which do not have a direct financial cost should be corrected
4. Generally, 80% of the quality control problems are justifiable for correction via costbenefit analysis. The remaining 20% are not financially worthy of improvement efforts
5. In order to minimize financial losses from quality control problems, all problems which have a measurable cost associated with them should be corrected

Q3. Lot tolerance percent defective (LTPD) is a level of lot quality specified by the ______________.

1. Consumer
2. Producer
3. Supplier
4. Sampling Plan

Q4. When conducting an ANOVA, the F-Value calculated from the data will always fall within what'range?

1. between negative infinity and infinity
2. between 0 and 1
3. between 0 and infinity
4. between 1 and infinity

Q5. Statistical Decision Making includes Pareto Analysis as a means of reducing errors in the total project process. Pareto Analysis ______________.

1. compares the error rate with the pass rate to determine the allowable number of errors per 1,000
2. compares the error rate of individuals to determine the compensation for bonuses
3. is a method of rejecting errors or variances from standards following self-inspection
4. is a procedure for ranking the errors to identify those contributing the most to failures [PMBOK p. B-2]
5. counts errors or failures to determine the added cost of all operations that do not meet the requirements

Q6. inspection is part of the ______________

1. Quality improvement
2. Quality circle
3. quality control
4. Quality Planning

Q7. In a double sampling plan, let d1 be the number of defects in the first sample and d2 be the number of defects in the second sample. Let c2 be the acceptance number for both samples. The condition for rejection is:

1. D1+d2
2. D1+d2>c2
3. D1*d2>c2
4. D1*d2

2. 1280 / 81
3. 5120 / 81
4. 1280 / 9

Q10. Q-Q plot is used to check:

1. Normality of the dataset
