比率P的假设检验及其应用
摘要:假设检验是统计推断的另一项重要内容,它与参数估计类似,但角度不同。参
数估计是利用样本信息推断未知的总体参数,而假设检验则是先对总体参数提出一个假设值,然后利用样本信息判断这一假设是否成立。本文将主要介绍总体比率的假设检验的原理和方法,以及其在各种生活实例中的应用,从而更深的了解假设检验在各种统计方法中的重要作用。

Hypothesis Testing and Its Application of Ratio P
Abstract:Hypothesis testing is another important content to statistical inference, and it is
similar to parameter estimation, but the Angle is different. Parameter estimation is use sample information to infer an unknown population parameter, and the hypothesis testing is a hypothesis is proposed first in the overall parameters, and then using the sample information to determine whether the hypothesis is established. This article mainly introduces the overall rate of the principle and method of hypothesis testing, and its application in all kinds of living examples, thus deeper understanding of the hypothesis testing plays an important part in all kinds of statistical methods.
