Multiple Choice Questions
The following items apply to determining sample sizes using random sampling from large populations for attributes sampling. Select the most appropriate response for each question.

(1) Increase.
(2) Remain the same.
(3) Decrease.
(4) Become indeterminate.
b. If all other factors specified in a sampling plan remain constant, changing the TER from 9% to 6% will cause the required sample size to
(1) Increase.
(2) Remain the same.
(3) Decrease.
(4) Become indeterminate.

(1) Population size
(2) Expected population exception rate
(3) Tolerable exception rate
(4) Acceptable risk of assessing control risk too low
