Generate n = 100 observations from the autoregression x_t=-0.9x_t-2)+x_t, Where {x_t } is white noise with σ^2 = 1. Next, apply the moving average v_t=(x_t+x_(t-1)+x_(t-2)+x_(t-3))/4 to x_t, the data you generated. Comment on the behavior of {x_t}, and how moving average changes this behavior. Hint: v = filter(x, rep(1/4, 4), sides=1) Repeat (a) but with x_t=cos〖(2πt/4)〗 Repeat (b) but with x_t=cos〖(2πt/4)〗+w_t Compare (a) to (c).

The sat and act tests use very different grading scales. the sat math scores follow a normal distribution with mean 518 and standard deviation of 118. the act math scores follow a normal distribution with mean 20.7 and standard deviation of 5. suppose regan scores a 754 on the math portion of the sat. how much would her sister veronica need to score on the math portion of the act to meet or beat regan's score?
