| 摘 要： | 对单个正态总体方差的假设检验是正态总体参数假设检验的重要组成部分.通过对原假设拒绝域的分析,讨论了总体均值未知与总体均值已知对原假设判断的影响,进而对论证的现象给出了合理的解释.

| Abstract: | The hypothesis testing of a single normal population variance is the important part of hypothesis testing of normal population parameter.In this paper,the impact of knows and unknown population means on the original hypothesis is discussed through the analysis of the rejection region.Then,the following phenomena are also reasonably explained. |
