| Abstract: | In this paper, we introduce three methods in the condition of small sample, which construct confidence intervals of the lognormal mean： PB method, P-value method and r^＊ method. We compare three methods which indicate r^＊ method is the best excellent than other two methods. At last, the result is applied by one example. |
