Confidence Intervals Based on Mean and Range

In some cases, we have a part of sampling informations. In this case the analysis of data via classical statistical methods is not possible and based on the information of various samples, we read some special analysis. In this article based on mean, maximum and minimum value from m random samples of a normal population with size n, we obtain an exact confidence interval for mean, where m=1 and m>l . The result is some tables, and the study represents confidence coefficient when the distribution is not normal.
