The number of customers served at a busy restaurant on Thursdays follows a Normal distribution with mean 6,385 and standard deviation 251.  Suppose we select a simple random sample of 36 Thursdays and use it to compute \overline{x}x, the average number of customers served on each of these Thursdays.  What is the probability that the number of customers served on a random Thursday exceeds 6,649?
