The assets​ (in billions of​ dollars) of the four wealthiest people in a particular country are 37, 35, 31, 19. Assume that samples of size n=2 are randomly selected with replacement from this population of four values. After identifying the 16 different possible samples and finding the mean of each​ sample, construct a table representing the sampling distribution of the sample mean. In the​ table, values of the sample mean that are the same have been combined.

2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.
