For testing the difference between two population proportion

For testing the difference between two population proportions, the pooled proportion estimate is found by taking:

a. the difference between the proportion of successes in each sample.

b. the proportion of successes from sample 1 plus the proportion of successes from sample 2.

c. the total number of successes in both samples divided by the total of both sample sizes.

d. None of these choices.
