5.(a) Simulate and plot a white noise process e_t~ iid N(0, 1) of length n = 100

(b) Simulate and plot a white noise process e_t~ iid c²(1) of length n=100

(c) For each of your simulated series in parts (a) and (b), create , plot thecorresponding random walk process Y_t= Y_t-1+ e_t, for t = 1,2,..., 100.

(d) Comment on the differences between the 2 simulated random walk processes in(c).
