Assume that the weight loss for the first month of a diet program varies between 6 pounds and 12 pounds, and is spread evenly over the range of possibilities, so that there is a uniform distribution. Find the probability of the given range of pounds lost.
Less than 11 pounds
----
6 sigma = (12-6) = 6
--
sigma = 6
===
u = (12+6)/2 = 9
------
z(11) = (11-9)/6 = 1/3
---
P(x < 11) = P(z < 1/3) = 0.6306
