The large sample confidence interval procedure for estimating $p _ { 1 } - p _ { 2 }$ requires the random samples to be selected independently.

Question

Quizplus · Accepted Answer

The assumption of independent random samples is necessary for the large sample confidence interval procedure for estimating the difference between two proportions ($p _ { 1 } - p _ { 2 }$). When the samples are not independent, the analysis can be more complex and may require other statistical methods.
