The formula for the standard error of $\hat { p } _ { 1 } - \hat { p } _ { 2 }$ used in hypothesis testing and confidence intervals is the same.

Question

Quizplus · Accepted Answer

The formula for the standard error differs between hypothesis testing and confidence intervals because hypothesis testing often assumes a pooled proportion, while confidence intervals use separate sample proportions.
