Answer

Final Answer: $\mu_{\bar{x}} = \boxed{80}$

Steps

Step 1 :Given the parameters of the population and sample size, we are asked to determine the mean of the sample means (denoted as $\mu_{\bar{x}}$) and the standard deviation of the sample means (denoted as $\sigma_{\bar{x}}$).

Step 2 :The given parameters are: population mean ($\mu$) = 80, population standard deviation ($\sigma$) = 24, and sample size (n) = 64.

Step 3 :The mean of the sample means is equal to the population mean. Therefore, $\mu_{\bar{x}} = \mu$.

Step 4 :Substituting the given value of $\mu$ into the equation, we get $\mu_{\bar{x}} = 80$.

Step 5 :Final Answer: $\mu_{\bar{x}} = \boxed{80}$
