Questions on a statistics exam are considered good questions provided the questions discriminate between students who have studied for the exam and those who have not studied. Suppose that on a particular statistics exam the students were separated into two groups, Group 1 that studied and Group 2 that had not studied. Data was collected and a 95% confidence interval for the difference in the proportion of those passing the exam from Group 1 that studied and the proportion of those passing the exam from Group 2 that had not studied. The confidence interval turned out to be (0.005, 0.125). Select the best answer.

Let p1p1 = the proportion of Group 1 students that passed the exam

Let p2p2 = the proportion of Group 2 students that passed the exam
