Question 1: Let X be the number of baseball tickets purchased per game by a randomly selected customer for a par- ticular venue and baseball season. Suppose the distribution of X is as follows: (a) (b) X 1 2 3 p(x) 0.1 0.4 0.3 4 0.2 Consider a random sample of size n = 2 (two customers), and let X be the sample mean number of tickets purchased. Obtain the probability distribution of X. Refer to part (a) and calculate P(X ≤ 3). Again consider a random sample of size n = 2, but now focus on the statistic R = the sample range. Obtain the distribution of R. (d) Refer to part (c), compute E(R).
