Confidence Intervals for the Difference of Two Proportions

[@CornyCobb]

In the equation you wrote (p̂1- p̂2) as the estimate in the equation, but then you did (p̂2-p̂1). Do you always subtract the smaller number from the larger number? Do you take the absolute value? It would be very helpful if you addressed this.

I am confused as to why the p-hat1 and p-hat2 were switched in computing the upper and lower bound.
