摘要
在单侧检验中,有时由于交换原假设与备择假设,会得到两个不同的假设检验结果.因此,先从理论上对检验结果进行分析,然后结合实例来阐述建立原假设和备择假设的一些方法.
In single-side hypothesis testing, the exchange of the null hypothesis and alternative hypothesis would induce two different testing results sometimes. The different testing results from the theories are analyzed, some methods on how to establish null hypothesis and alternative hypothesis are formulates with some examples.
