Difference Between Two Proportions

Activity Overview

Students use confidence intervals to estimate the difference of two population proportions. First they find the intervals by calculating the critical value and the margin of error. Then, they use the 2-propZInterval command. Students find confidence intervals for differences in proportions in real-life situations and use them to make judgments about certain claims. Last, they determine required sample size, n, when given a confidence interval and margin of error.
