72. Machine capability studies on four machines yielded the following
information:

Machine Average (X) Capability (6s)
#1 1.495 .004″
#2 1.502 .006″
#3 1.500 .012″
#4 1.498 .012″

The tolerance on the particular dimension is 1.500 ± .005”. If the
average value can be readily shifted by adjustment to the machine,
then the best machine to use is:

a. Machine #1.
b. Machine #2.
c. Machine #3.
d. Machine #4.

73. How should measurement standards be controlled?
1. Develop a listing of measurement standards with nomenclature and
number for control.
2. Determine calibration intervals and calibration sources for
measurement standards.
3. Maintain proper environmental conditions and traceability of
accuracy to National Bureau of Standards.

a. 1 and 2 only
b. 1 and 3 only
c. 2 and 3 only
d. 1, 2, and 3
74. When making measurements with test instruments, precision and
accuracy mean:
a. the same.
b. the opposite.
c. consistency and correctness, respectively.
d. exactness and traceability, respectively.
e. none of the above
75. Calibration intervals should be adjusted when:
a. no defective product is reported as acceptable due to measurement
errors.
b. few instruments are scrapped during calibration.
c. the results of previous calibrations reflect few “out of tolerance”
conditions during calibration.
d. a particular characteristic on the gauge is consistently found out of
tolerance.
