The article "Freedom of What?" (Associated Press, February 1, 2005) described a study in which high school students and high school teachers were asked whether they agreed with the following statement: "Students should be allowed to report controversial issues in their student newspapers without the approval of school authorities." Researchers hypothesized that the long-run proportion of high school teachers who would agree with the statement would differ from the long-run proportion of high school students who would agree. Two random samples - 8,000 high school teachers and 10,000 high school students - were selected from high schools in the U.S. It was reported that 39% of the teachers surveyed and 58% of the students surveyed agreed with the statement.
-A simulated null distribution of 1,000 differences in proportions created by using the
Two Proportion applet is shown below.
Use the 2SD method to find a 95% confidence interval for the difference in long-run proportion who would agree with the statement between Students and Teachers (Students - Teachers).
(____(1)____, ____(2)____)
