| Abstract: | Establishing null hypothesis and alternative hypothesis is the first step in hypothesis test.How to establish null hypothesis and alternative hypothesis in hypothesis test is a trouble problem for students and beginners.According to Neyman-Pearson criteria,null hypothesis and alternative hypothesis aren’t in the same status.How to set up null hypothesis and alternative hypothesis in hypothesis test are discussed in this paper.Several principles are given. |
