For each plot, please match it with one corresponding time series (that is, choose A, B, C, or D in below) and specify whether it is an ACF plot or plot of the original time series (circle one). Your answer: Plot (1): Plot (2): Plot (3): Plot (4): ACF plot or ACF plot or ACF plot or ACF plot or original series plot original series plot original series plot original series plot (circle one) (circle one) (circle one) (circle one)

Q2s Let W₁, W2,..., be white noises. The above four plots are two plots of the
original time series and two ACF plots for two time series from the following 4 time
series:
5 10 15 20 25
(A) xt=w₁ +0.5wt-1,
1≤t≤ 1000
(B) xt=Wt+0.5wt-1,
1≤t≤ 10000
(C) x = 0.7xt-1+we, 1 ≤ t ≤ 1000
(D) xt1.01xt-1+wt,
1≤ t ≤ 1000
