Simulate each series in the previous table (Exercise 7) with the specified white noise variance:

i. Find a1 and a2 and verify they meet the conditions for stability.

ii. Compute all values on the table.

iii. Simulate and plot the time series.

iv. Produce the acf() graph.

v. Verify
 and the variance for the series [use var() in R to get the variance of the time series].
