| Abstract: | In this paper, goodness of fit test and homogeneity test of life distribution of a type littlelamp of factory A and B are conducted. Analysis results indicate their life foll0ws not identical population,but follows all the lognormal distribution. Based on reliability assessment of little lamp of factory A andB, selecting the little lamp of factory A is suitable. |
