A modified robust confidence interval for the population mean of distribution based on deciles

Abstract The confidence interval is an important statistical estimator of population location and dispersion parameters. paper considers a robust modified interval, which adjustment the Student’s t based on decile mean standard deviation for estimating skewed distribution. efficiency proposed evaluated basis extensive Monte Carlo simulation study. coverage ratio average width are compared with certain existing widely used intervals. results show that, in general, estimator’s performance highly effective. For illustrative purposes, three real-life data sets analyzed, which, to extent, support findings obtained from Thus, we recommend that practitioners use when generated by normal or
