In this paper we study the two-tailed test problem for the normal distribution. We also get a new testing method, namely F-test. 研究了正态分布总体均值的双边假设检验问题,得到了一个新的检验方法&F检验法。
Using correlation analysis of multivariate statistical to calculate the correlation between factors and the tank bottom corrosion, and testing the correlation by two-tailed test. 应用多元统计理论中的相关分析计算各因素与储罐底板腐蚀状态之间的相关性,并采用双尾检验对相关性的显著性进行验证。
