Peter kindly took the time to reply to your first post, but that should not be an indication that you have tacit approval to continue to post such questions here. If these are indeed homework questions, seek assistance from your professor or other academic support resources. If they are not, seek out other more general online resources such as StackExchange/CrossValidated (http://stats.stackexchange.com/questions). Regards, Marc Schwartz

What do you know about these time series, specifically about their joint distribution? Also, is "t" a single time point or a sequence of time points? In the first case, we are just dealing with a bivariate distribution. Finally, what do you mean by "conditional quantile", conditional on what?
