(5 points) The Daily Show. A 2010 Pew Research foundation poll indicates that among 1,099 college graduates, 33% watch The Daily Show. Meanwhile, of the 1,110 people in the poll with a high school degree but no college degree, 22% watch The Daily Show. A 95% confidence interval for pCollegeGrad−pHighSchoolpCollegeG rad−pHighSchool, where pp is the proportion of those who watch The Daily Show, is (0.07, 0.15). Based on this information, determine if the following statements are true or false, and explain your reasoning if you identify the statement as false.

1. There is a 95% chance that pCollegeGrad−pHighSchoolpCollegeG rad−pHighSchool is between 0.07 and 0.15. ? True False

2. We are 95% confident that 7% less to 15% more college graduates watch The Daily Show than those with a high school degree or less. ? True False

3. 95% of random samples of 1,099 college graduates and 1,110 people with a high school degree or less will yield differences in sample proportions between 7% and 15%. ? True False

4. 90% confidence interval for pCollegeGrad−pHighSchoolpCollegeG rad−pHighSchool would be wider. ? True False

5. A 95% confidence interval for pHighSchool−pCollegeGradpHighScho ol−pCollegeGrad is (-0.15,-0.07). ? True False
