Unformatted text preview: C Determine the standard error of the sampling distribution of the differences with the new sample sizes. What happened to the standard error when we increased the sample sizes? D Determine the Z ­Score for a difference in sample proportions of 0. E Would this result be unusual? F What is the probability of observing a difference in sample proportions less than 0 under these circumstances? © 2011 THE CARNEGIE FOUNDATION FOR THE ADVANCEMENT OF TEACHING A PATHWAY THROUGH STATISTICS, VERSION 1.6, STATWAY™  ­ STUDENT HANDOUT STATWAY STUDENT HANDOUT | 6 Lesson 9.1.2 Using Technology to Explore the Sampling Distribution of the Differences in Two Proportions TAKE IT HOME In considering differences in sample proportions, we often assume that there is no difference in population proportions. That is, we assume that p1  ­ p2 = 0. Then, using what we know about the normality of the distribution of !! − !! , we can calculate the probability of observing particular values of the sample proport...
