Shоw Yоur Wоrk аnd Submit. The аssets (in billions of dollаrs) of the four wealthiest people in a particular country are 38, 29, 28, 10. 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 find 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. (Type integers or fractions.) Sample Mean Probability 38 33.5 33 29 28.5 28 24 19.5 19 10 The mean of the population, , is (greater than, less than, equal to) the mean of the sample means, . The sample means (do not, do) target the population mean. In general, sample means (do not, do) make good estimates of population means because the mean is (an unbiased, a biased) estimator.
