For sample sizes of 30 elements or more, taken from a large population, if you plot the arithmetic means of each of the samples on a graph (x-axis represents the sample mean; y-axis represents the number of times that value occurs among all the samples or the probability of that value occurring among all the samples), they will follow a normal curve distribution and the mean value of that distribution will be equal to the mean value of the population from which the samples were taken. This finding is known as the___________theorem?
