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%).

The achieved allowance for sampling risk is 4%, which means that there is a 4% chance that the true deviation rate in the population is higher than the computed upper deviation rate. Since the tolerable deviation rate is 4.5%, and the computed upper deviation rate already includes the achieved allowance for sampling risk, we can conclude that the sampling plan has met the desired confidence level and the tolerable deviation rate. Therefore, no further action is necessary.

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