假设检验的案例与应用摘要假设检验又称显著性检验，是统计推断的重要组成部分，其目的是在一定假设的基础上，用样本推断总体，检验实验组与对照组之间是否存在差异，差异是否显著。在工程实践中，为了保证系统和部件的可靠性，需要建立相应的数学模型，采用概率分布和假设检验的方法进行必要的计算。本文总结了假设检验处理检验数据的过程，并举例说明了该过程的应用。本文首先分析了假设检验的基本思想、步骤、检验原理以及假设检验的方法等重点讨论了假设检验在生产实践中的使用状况，丰富了假设检验在生活中的应用方面的结果。关键词：假设检验；参数分析；实例验证The cases and applications of hypothesis testAbstractHypothesis testing, also called significance test, is an important part of statistical inference. The purpose of hypothesis testing is to infer the population with samples on the basis of certain assumptions, to test whether there is a difference between the experimental group and the control group, and whether the difference is significant. In engineering practice, in order to ensure the reliability of the system and components, it is necessary to establish corresponding mathematical models and use the methods of probability distribution and hypothesis testing for necessary calculations. Firstly, this paper introduces the basic ideas, steps, testing principles and methods of hypothesis testing, etc. Then we focus on discussing the applications of hypothesis testing in production practice which extends the related results of hypothesis testing in real life.Keywords：Hypothesis test; parameter analysis; case study目录摘要..........................................................................IAbstract.....................................................................II1 引言........................................................................12 假设检验的基本思想与方法....................................................12.1 假设检验的基本思想...........
