Question

If the sampled population distribution is skewed, then in most cases the sampling distribution of the mean can be approximated by the normal distribution if the sample size n is at least 30.A.TRUEB.FALSE

Answer 1

A.TRUE

Because of the Central Limit Theorem

Explanation:

The Central Limit Theorem estabilishes that, for a random skewed variable X, with mean
`\mu` and standard deviation
`\sigma`, the sampling distributions of the mean with size n of at least 30 can be approximated to a normal distribution with mean
`\mu` and standard deviation
`s = (\sigma)/(√(n))`

So the correct answer is:

A.TRUE
