遵循ISO 2854，提出了II型风险的概念，即当无效假设为假时，不拒绝该假设的概率。处理一个均值与给定值（方差已知或未知）、两个均值（方差已知或未知）、一个方差与给定值以及两个方差的比较，给出给定备选方案和给定样本量的II型风险曲线集，并确定给定备选方案和II型风险给定值的待选样本量。

Follows on from ISO 2854 and puts forward notions of the type II risk, the probability of not rejecting the null hypothesis when it is false. Deals with comparison of a mean with a given value (variance known or unknown), of two means (variance known or unknown), of a variance with a given value, and of two variances, and gives sets of curves for these type II risk for a given alternative and given size of sample and to determine the size of sample to be selected for a given alternative and a given values of type II risk.
