Question

The assets (in billions of dollars) of the four wealthiest people in a particular country are 37, 35, 27, 16. Assume that samples of size n 2 are randomly selected with replacement from this population of four values a. 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 Probability Probability 37 36 35 32 31 27 26.5 25.5 21.5 16 (Type integers or fractions.) b. Compare the mean of the population to the mean of the sampling distribution of the sample mean The mean of the population, 26.50, is equal to the mean of the sample means, 26.50 (Round to two decimal places as needed.)

The mean of the​ population, 28.75​, is equal to the mean of the sample​ means, 28.75.

Recall that the mean of a set of data is the measure of center found by adding the data values and dividing the total by the number of data values.

(37+35+27+16) ÷ 4 = 28.75
