Question: Consider a research project in which we take a random sample from a population, and administer a survey, asking about support for various criminal justice
Consider a research project in which we take a random sample from a population, and administer a survey, asking about support for various criminal justice policies, such as GPS monitoring for sex offenders or forms of gun control. When we report findings from the data, we might report that the proportion supporting permit-to-purchase firearm legislation is 50%, with a 95% confidence interval of 45% to 55%. For this scenario, please address the following: 1) Drawing on the concept of sampling error, describe why we would want to add a confidence interval to our point estimate of 50%. 2) Using the logic of sampling distributions, describe how we are able to make statements about confidence intervals, even though we have only collected data from a single sample (hint: think about the assumptions we need to make for a confidence interval to be accurate).
