Question 1182733
<pre>
A confidence interval always has p̂ in the exact middle of the interval.

To find the middle, average the lower and upper bounds, 0.444 and 0.888:

{{{(0.444+0.888)/2 = 0.666}}}

So p̂ = 0.666

The value of E is the difference in absolute value between p̂ and either
bound. 

E = |0.888-0.666| = |0.444-0.666| = 0.222

so 

p̂±E = 0.666 ± 0.222
