I recently ran into this problem when assisting my girlfriend with her
studies for an exam in basic statistics, but I've been unable to solve
it:
I have a random variable X normally distributed with known mean and
standard deviation, say, X~N(2, 0.5). If I make two samples from this
distribution, how do I find the probability of the absolute difference
between these samples being larger than a given number, say 1? (I think
the textbook example involved retrieving two cabbages from a field and
weighing them, X being the weight)
Any help would be much appreciated.
Regards,
