ヾ(◍°∇°◍)ノ゙你好同学,
题目考的是中心极限定理,无论总体分布,当样本容量足够大时,样本均值的分布趋近于正态分布
If the distribution (of the population from which samples of size n are drawn) is positively skewed (and given that the sample size, n, is large), the sampling distribution of the sample means is most likely to have a distribution that is approximately normal.
