Surveys have become an important component of American life. They directly affect us in so many ways, including public policy, the television shows we watch, the products we buy, and the political leaders we elect. Because surveys are now such an integral part of our lives, it is important that every citizen has the ability to
interpret survey results. Surveys are the focus of this project.
Use the following survey information to answer the questions below. There are no "right" or "wrong" answers, as long has you back up your answer with scientific evidence. Here, evidence is the process and formulas we have used throughout Chapter 8.
A recent Harris survey of 1961 adults showed that 76% have registered for the "Do Not Call" registry, so that telemarketers do not phone them. Use a 95% confidence interval.
