For an Attributes Sampling Plan,the Tolerable Deviation Rate Is 4

Multiple Choice

For an attributes sampling plan,the tolerable deviation rate is 4.5%,the computed upper deviation rate is 7%,the sample deviation rate is 3%,and the desired confidence level is 95%.What is the allowance for sampling risk included in the computed upper deviation rate?

A) 1.5%.
B) 3%.
C) 4%.
D) 5%.
The computed upper deviation rate includes the sample deviation rate and the allowance for sampling risk. Therefore, if we subtract the sample deviation rate from the computed upper deviation rate, the difference is the achieved allowance for sampling risk, or 4% (7% - 3%) .
