Daily output of Marathon's refinery is normally distributed with a mean of 232000 barrels of crude oil per day with a standard deviation of 7000 barrels.
---------------------------------------------
What is the probability of producting at least 232000 barrels?
P(0 < z) = 0.50
----------------------------
Between 232000 and 239000 barrels?
P (232000 < x < 239000) = P(0 < z < [(239000-233200/7000]) = P(0
---------------------------------
I have a feeling that you have posted the wrong standard deviation. Are you
sure it's not 70,000?
