A sampling distribution refers to the distribution of:

A. a sample

B. a population

C. a sample statistic

D. a population parameter

E. repeated samples

F. repeated populations

The answer is a population parameter.

Step-by-step explanation:

Population can include people, but other examples include objects, event, businesses, and so on. Population is the entire pool from which statistical sample is drawn.

A parameter is a value that describes a characteristics of an entire population, such as population mean, because you can almost never measure an entire population, you usually don't know the real value of a parameter.

Consider all possible sample of size N that can be drawn from a given population (either with or without replacement). For example, we can compute a statistics (such as the mean and the standard deviation) that will vary from sample to sample. In this manner we obtain a distribution of statistics that is called Sampling distribution.
