Figure 1 shows time series plots of two time series processes (Y) and {X} for T = 500, and Figure 2 provides the result of regression of Y on X. (a) Based on Figures 1 and 2, do you think we can conclude that X has a positive effect on Y? (b) If you answered the above question with "No", how would you estimate the partial effect of X on Y? If you answered the above question with "Yes", then explain how X affects Y.
