摘要

In this paper we consider and propose some confidence intervals for estimating the mean or difference of means of skewed populations. We extend the median t interval to the two sample problem. Further, we suggest using the bootstrap to find the critical points for use in the calculation of median ( intervals. A simulation study has been made to compare the performance of the intervals and a real life example has been considered to illustrate the application of the methods.
