1 Dept of Bioenvironmental Systems Engineering National Taiwan University Lab for Remote Sensing Hydrology and Spatial Modeling STATISTICS Interval Estimation Professor Ke-Sheng Cheng Department of Bioenvironmental Systems Engineering National Taiwan University

2 Lab for Remote Sensing Hydrology and Spatial Modeling Dept of Bioenvironmental Systems Engineering National Taiwan University Variation of sample means 6 random samples (sample size n= 50) of a normal density with unit variance and an unknown mean [N( , 1)]. 6 random samples (sample size n= 500) of a normal density with unit variance and the same unknown mean [N( , 1)]. Examine the variation of sample means.
