For manufactured items sold by weight or volume, this article considers mixed acceptance criteria that put limits on the sample mean or on an upper confidence limit based on the sample mean and on the number of individual sample units that are nonconforming. For a normally distributed quality characteristic of interest, this article develops lower confidence limits for the mixed acceptance criteria applying the concept of a generalized pivotal quantity and applying a bias‐corrected and accelerated parametric bootstrap. The accuracy of the confidence limits is assessed using estimated coverage probabilities, and the results are illustrated with an example.

使用混合接受标准进行合规性测试的置信度限制

对于按重量或体积出售的制成品，本文考虑了混合接受标准，该标准对样本平均值或基于样本平均值和不合格的单个样本单元的数量设置了置信上限。对于感兴趣的正态分布质量特征，本文针对广义验收量的概念并应用经过偏差校正和加速的参数自举，为混合接受标准制定了较低的置信度。使用估计的覆盖概率评估置信度限制的准确性，并通过示例说明结果。
