When the hypothesized difference of the population proportions is equal to 0, we can estimate the standard error of the difference using the pooled proportion, which is the mean of the two sample proportions. Additionally, we can use the confidence interval to implement the test if the difference of the population proportions is equal to 0. Therefore, both options B and C are correct. The matched-pairs approach (option A) is used when we have paired data, and it is not relevant when testing the difference of population proportions.
