Let X[k] = A:(-1)k be a random process (RP) where A has pmf: = 1 ha = 5 8 1 = 1 8 5 a = -1 = g, a = =1 fa(a) = g, a 1 a a=0 10, otherwise) a) Sketch 3 different samples of this RP for the range k = 0,...,4. Note that there are infinitely many right answers to this problem (as well as wrong answers!). Clearly label everything. b) Determine and plot (from 0 to 4) the mean function Jof this random process. Show your work carefully. Is it possible that Xk is wide-sense stationary (WSS)? Justify your answer.
