Definition 6 单边置信区间 one-sided confidence interval 与置信区间类似,我们有两个单边置信区间\\ (L,\infty),(-\infty,U),满足:\\ \mathbf{P}(L<g(\theta))\geq1-\alpha\\ \mathbf{P}(U>g(\theta))\geq1-\alpha\\ 二、运用 Example 1 正态分布均值的置信区间 confidence intervals for the...

(正文要超过200字才能发。。我随便贴点讲稿来) 这时,我们回到均值抽样分布实验中。假设,我们现在有权限打开excel表了,并且算出总体的真实均值μ=137.41分。然后,对这个excel表进行了1000次,样本容量n=20的抽样,获得如图所示的均值抽样分布。我们发现,均值抽样分布的对称轴,正是总体的真实均值μ。

在深入理解了T检验的核心理念后，我们今天将揭开置信区间这一统计学瑰宝的面纱。置信区间，一个看似简单却蕴含深意的概念，用英文直译就是confidence interval，它揭示了我们对于抽样样本平均值的信赖程度和其可能的波动范围。理解置信区间，就像测量信心的尺度 想象一下，我们对样本的平均值拥有多大的把握？
