Question 1010875
mean 32.2
sd=0.1
z for 32 oz=(32-32.2)/0.1=-0.2/0.1=-2
It is the probability the z score is >=-2 or 0.9772
================
More than 32.2 oz is 50%
===============
Between 31.0 and 32.2 ounces is 
a z-score of -12 and a z-score of 0.  That is 50% as well.  
================
z-score here is (32.0-32.2)/0.1/sqrt (9)
That is 3(-2)=-6 and the probability is essentially zero.
