Random samples of size 64 are taken from an infinite population whose mean and standard deviation are 24 and 6.4, respectively.
umka2103 [35]

Answer:

Mean 24, standard error 0.8

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean \mu and standard deviation \sigma, the sample means with size n of at least 30 can be approximated to a normal distribution with mean \mu and standard deviation, also called standard error s = \frac{\sigma}{\sqrt{n}}

In this problem, we have that:

\mu = 24, \sigma = 6.4, n = 64

What are the mean and the standard error of the sample mean?

By the Central Limit Theorem, mean 24 and standard error s = \frac{6.4}{\sqrt{64}} = 0.8
