样本均值偏离总体均值的概率的精确估计的推广

摘要

In ＂An extension of Chebyshev inequality and its applications＂,the example 3 diccussed precise estimation of the deviation probability between sample mean with population mean,in this paper,we will extend the precise estimation of the deviation probability between sample mean X（1 n） with population mean μ to the case between sample mean X（δ）,δ∈（0,∞） with population mean μ by the property of limitation.%文献[1]中例3讨论了样本均值偏离总体均值的概率的精确估计.利用极限的性质将样本均值X（1n）偏离总体均值μ的概率的精确估计推广至样本均值X（δ）δ,∈（0,∞）偏离总体均值μ的情况.
