文档介绍：摘要
假设检验是抽样推断中的一项重要内容。在实际应用的很多时候,我们并不能知道总体的详细情况,而是通过对从总体中抽取的样本的研究来对总体做出判断。这就需要我们先做出假设,然后根据一定的检验方法和概率原则对假设做出判断,得出总体的情况。
运用抽样数据进行推断已经成为现代社会一种普遍适用并且强有力的思考方式。本文阐述了假设检验的意义,概念,基本原理和基本实施步骤,并将假设检验理论应用于经济分析中,通过对抽样的数据进行推断分析,为以后的管理决策提供依据,对指导经济分析具有十分重要的意义。

ABSTRACT
The hypothesis testing is an important part of the sample inferred. In many cases of practical application, we can not know the overall situation, but through the study of a sample taken from a population to make a judgment on the overall. This requires us to make assumptions first,and then make a judgments to the assumptions based on certain test methods and probability principles.
The use of sampling data extrapolation has e a universal and powerful way of thinking of the modern society. This paper describes the significance of the hypothesis testing, concepts, basic principles and basic implementation steps, and hypothesis testing theory used in economic analysis, by extrapolation analysis, sample data provide the basis for future management decisions, to guide economic analysis hasof great significance.
Key words:hypothesis testing; statistical inference; economy; two types of errors
