where 
is the sample proportion, 
is the sample size, and 
is the critical score for the desired confidence level.
and a sample proportion of 
. Our critical score for a 99.7% confidence level would be 
![CI=\hat{p}\pm z^*\sqrt{\frac{\hat{p}(1-\hat{p})}{n} }=0.58\pm 2.9677\sqrt{\frac{0.58(1-0.58)}{80} }=[0.4162,0.7438]](/tpl/images/1350/2148/89614.png)
