Question 449666
A machine is set to pump cleanser into a process at the rate of 10 gallons per minute. Upon inspection, it is
learned that the machine actually pumps cleanser at a rate described by the uniform distribution over the interval 9.5 to 12.5 gallons per minute. 
------
Mean = 10---
6*sigma = 12.5-9.5 = 3
---
sigma = 1/2
-----

Find the probability that between 10.0 gallons and 11.0 gallons are
pumped during a randomly selected minute.
---
z(11) = (11-10)/3 = 1/3
z(10) = (10-10)/3 = 0
---
P(10< x < 11) = P(0< z < 1/3) = 0.1306
