Question 185890
find the area under the normal curve that has mean 100 and standard deviation 500 that lies between the values x=-150 and x=1,200.

Do you need to know how to work this problem or just what the answer is?
------------
Using a TI-83 you would get: normalcdf(-150,1200,100,500) = 0.6776
