Properties of a statistic are typified by its sampling distribution. Ex : The probability distribution shown here describes a population of measurements that can assume values of 0, 2, 4, and 6, each of which occurs with the same relative frequency. a. List all the different samples of n = 2 measurements that can be selected from this population. b. Calculate the mean of each different sample listed in part (a). c.
