Assume a series of 1000 data points. The mean of the first 500 points is 2, with s.d. 1. What is the probability of finding mean > 0, on the second 500 data points?
Extra information:
The first 500 points are approximately normally distributed.
The first 500 points are not independently distributed, for most points: point(t) is similar to point(t+1)
