All possible samples of size n are selected from a population and the mean of each sample is determined. What is the mean of the sample means?

The population mean

Step-by-step explanation:

Sample Mean is the mean of of the selected samples while the population Mean is the mean of all the population. The mean of the sampling distribution of the sample mean is equal to the mean of the original distribution (that is the sample mean is equal to the population mean).

The mean of the sample means is always approximately the same as the population mean

f(x) is   are being squared

g(x) is   increasing by 2

h(x) is adding .25 each time

k(x) is taking the square root

f(x) and k(x) are exponential functions
