Meanwhile, by using interval estimation instead of the conventional point estimation, the lower and upper confidence limits, the confidence intervals of structure concrete strength are derived.
运用区间估计方法代替传统的点估计方法，导出结构混凝土强度的置信上限、下限和置信区间。

In the case of K type interval censored data, the lowerconfidence limit of parameter is studied based on the order relation established in the sample space.
基于K型区间删失数据，利用样本空间排序法给出参数优良的置信下限和计算置信下限的递推公式。

In the final post hoc test of 21-year-old confidence, the normal distribution (95% confidenceinterval) level is lower than other ages.
