represent the critical value
The confidence interval for the difference of two proportions would be given by this formula
For the 95% confidence interval the value of 
and 
, with that value we can find the quantile in the normal standard distribution and we got.
Replacing into the formula we got:
And the best option for this case would be:
A. 0.050 to 0.112.
