<PRE><B>Question 1182336</B>
average (mean) is 949
standard deviation is 100
you want to find the probability that a randomly selected computer costs more than 1200.


z-score = (x - m) / s
x is the raw score
m is the mean
s is the standard deviation


formula becomes:


z = (1200 - 949) / 100 = 2.51


probability of a price greater than that would be .0060365747 = .006 rounded to 3 decimal places.
