1 Japanese quality control has improved dramatically in the last 30 years for all of the following reasons except:
A the use of quality circles.
B small, continuous improvements in quality control.
C the use of worker suggestion systems.
D the use of quality control charts. 来源：www.examda.com
E focusing quality control efforts on production outputs.
ans:E
2 Control chart theory is based on the differentiation of the causes of variations in quality. Variations may be produced by assignable causes. All of the following are examples of assignable causes except:
A differences among machines.
B differences among workers.
C differences among materials.
D differences in each of these factors over time.
E None of the above (all are examples)
ans:E
3 The rule of seven used by quality control engineers states that if a run of seven or more samples lays on one side of the process mean, then the process is out of control. What is the probability that this condition is the result of random variations.
A 14.30%
B 3.12%
C 2.73% www.Ｅxamda.CoM
D 1.56%
E 0.78%
ans:D
4 Two sources of variation in the length of hex bolts exist. Production variation and measurement error. The QC manager knows that the standard deviation from these sources is 0.24" and 0.43" , respectively. What is the total standard deviation.
A .10 inch.
B .19 inch.
C .34 inch.
D .49 inch.
E .67 inch.
ans:D
5 Affinity diagrams are used to:
A determine if a process is in control.
B determine root cause.
C show the relationship among variables.
D categorize large amounts of data.

9 For a given characteristic in a construction process, the standard deviation associated with production variation is 0.8", and the standard deviation associated with measurement variation is 0.6". The total standard deviation for this characteristic is:
A 1.4"
B 1.2".
C 1.0"
D 0.8"
E 0.2"
ans:C
10 Assignable cause or special variation is:
A is indicated when a point falls outside the control limits.
B is indicated when a point falls outside the specification limits.
C is indicated when a run of seven or more points fall above the center line of a standard control chart.
D is indicated when a run of seven or more points fall below the center line of a standard control chart.
E A, C, and D.
ans:E www.Ｅxamda.CoM
11 Quality control charts show a characteristic of the product or service against:

B customer requirements.
C control limits based on three standard deviations in each direction.
D control limits based on six standard deviations in each direction.
E A and D only
ans:C
