The merits of the proposed test are numerically compared with the existing tests - the James second order test, the Welch test and the Alexander-Govern test - with respect to their sizes and powers in different combinations of parameters and various sample sizes. The simulation results demonstrate that the proposed method is satisfactory: its type I error probability is very close to the nominal level. We illustrate these approaches using a real example.}, keywords = {Actual size,Computational Approach Test,Log-normal Distribution,Power}, url = {https://jsm.yazd.ac.ir/article_1698.html}, eprint = {https://jsm.yazd.ac.ir/article_1698_9aa57d69c55d8fc669172a7e1b903e05.pdf} }
