Question 519876: the average flight from point a to point b takes 200 minutes with a standard deviation of 10 minutes what is the probability that a flight will take between 197 and 205 minutes? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! the average flight from point a to point b takes 200 minutes with a standard deviation of 10 minutes what is the probability that a flight will take between 197 and 205 minutes?
-------------
z(197) = (197-200)/10 = -3/10
z(205) = (205-200)/10 = 1/2
----
P(197 < x < 205) = P(-3/10 < z < -1/2) = 0.3094
