C The central limit theorem tells us that for a population with a mean m and a finite variance σ2, the sampling distribution of the sample means of all possible samples of size n will approach a normal distribution with a mean equal to m and a variance equal toas n gets larger. 反馈...

The Central Limit Theorem (CLT) is one of the most remarkable results in probability theory because it’s not only very easy to phrase, but also has very useful applications. The CLT can tell us about the distribution of large sums of random variables even if the distribution of the random...
