2022-09-13 22:45題干中已經(jīng)提到了是positive skewed，為什么還能選C？既然已經(jīng)右偏，那就不是正態(tài)分布了啊

ヾ(?°?°?)??你好同學(xué)，
題目考的是中心極限定理，無(wú)論總體分布，當(dāng)樣本容量足夠大時(shí)，樣本均值的分布趨近于正態(tài)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.
