A lot of 1,000 items is on the loading dock. A single-sampling plan calls for a sample size of 10. The following table gives the probability of acceptance for the plan over a range of possible quality levels.
What is the average outgoing quality limit for this plan?
A) less than or equal to 0.018
B) greater than 0.0180 but less than or equal to 0.0200
C) greater than 0.0200 but less than or equal to 0.0220
D) greater than 0.0220

According to the given table, the sample size of 10 and probability of acceptance at 0.0180 is 0.074 and the probability of acceptance at 0.0200 is 0.085. Therefore, the average outgoing quality limit falls between these two values, making option B the correct choice.
