摘要
讨论当总体为两点分布时其样本均值偏离其总体均值的概率,并给出精确估计.随着样本容量的增大,这种偏差以指数收敛速度趋于零.
In this paper, we estimate precisely the deviation of the sam population mean when the population distribution is a two-point distribution. deviation tends to zero at an exponential speed as the sample size increases. pie mean from its We show that this
