Q1: Unbiasedness Consider a discrete random variable X with pmf given by P(X = 2) = P The distribution P(X = 4) = 2p of X is P(X = 6) = 3p UNKNOWN. P(X = 8) = 4p P(X = 10) = 1- 10p where p is an UNKNOWN real number in (0, 0.1). Answer the following questions with two copies, X] and X2, of X. a) Use a table to show the sampling distribution of S-1. b) Use the result in (a) to show that S._ is unbiased for of
