问题如下：
A population has a non-normal distribution with mean μ and variance σ2. The sampling distribution of the sample mean computed from samples of large size from that population will have:
选项：
A.the same distribution as the population distribution.
its mean approximately equal to the population mean.
its variance approximately equal to the population variance.
解释：
B is correct. Given a population described by any probability distribution (normal
or non-normal) with finite variance, the central limit theorem states that the
sampling distribution of the sample mean will be approximately normal, with the
mean approximately equal to the population mean, when the sample size is large.
A改成服从normal distribution 对吗
