摘要
Abstract
There are two problems existing in the ground density test.One problem is that using the protected conclusion as a null hypothesis based on statistical theory can not obtain a convincing qualified conclusion for the ground density test,and the other problem is that the pivot quantity of the test is not clear.The two problems are analyzed and discussed,and the inverse null hypothesis is proposed to be adopted.At the same time,for the two expressions of ground density,the non-central t-distribution and x2 distribution test methods should be used respectively.The example proves that the test conclusion has better credibility.The viewpoint of the inverse null hypothesis can be popularized and applied in one-sided test problems such as flight reliability and others in qualification tests.关键词
