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. 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.Analyzing the Data1. Use the survey results to construct a 95% confidence interval estimate ofthe percentage of all adults on the “Do Not Call” registry.2. Identify the margin of error for this survey.3. Explain why it would or would not be okay for a newspaper to make thisstatement: “Based on results from a recent survey, the majority of adults are not on the ‘Do Not Call’ registry.”4. Assume that you are a newspaper reporter.Write a description of the survey results for your newspaper.5. A common criticism of surveys is that they poll only a very small percentage of the population and therefore cannot be accurate. Is a sample of only 1961 adults taken from apopulation of 225,139,000 adults a sample size that is too small? Write an explanation of why the sample size of 1961 is or is not too small.6. In reference to another survey, the president of a company wrote to the Associated Press about a nationwide survey of 1223 subjects. Here is what he wrote: When you or anyone else attemptsto tell me and my associates that 1223 persons account for our opinions and tastes here in America, I get mad as hell! How dare you! When you or anyone else tells me that 1223 people represent America, it is astounding and unfair and should be outlawed. The writer of that letter then proceeds to claim that because the sample size of 1223 people represents 120 million people, his single letter represents 98,000 (120 million divided by 1223) who share the same views. Do you agree or disagree with this claim? Write a response that either supports or refutes this claim.
