Suppose that a study of elementary school students reports that the mean age at which children begin reading is 5.4 years with a

Tpy6a [65]

Answer:

By the Central Limit Theorem, the mean of the sampling distribution of sample means would be 5.4 years.

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In this problem, we have that:

The mean for the entire population is 5.4 years.

So, by the Central Limit Theorem, the mean of the sampling distribution of sample means would be 5.4 years.
