<PRE><B>Question 86399</B>
For a sample of size n=60, proportion p-hat=0.35, and at a 95% confidence level, the lower bound of the proportion is... 
----------------
p-hat-E is the lower bound
--------------
Since p-hat = 0.35 s=sqrt(0.35*0.65/60) = 0.06157
---------
For 95% confidence z* = 1.96
----------------
Therefore E = 1.96*0.06157 = 0.1206899..
-----------
Therefore lower bound = 0.35-0.1206899 = 0.22931..
================
