Let X be the number of packages being mailed by a randomly selected customer at a certain shipping facility. Suppose the distribution of X is as follows: x 1 2 3 4 p(x) .4 .3 .2 .1 a. Consider a random sample of size n = 2 (two customers), and let be the sample mean number of packages shipped. Obtain the probability distribution of . b. Refer to part (a) and calculate c. Again consider a random sample of size n = 2, but now focus on the statistic R = the sample range (difference between the largest and smallest values in the sample). Obtain the distribution of R. [Hint: Calculate the value of R for each outcome and use the probabilities from part (a).] d. If a random sample of size n = 4 is selected, what is ? (Hint: You should not have to list all possible outcomes, only those for which
