Question: Web-based exercise. Search the Web for a recent poll in which the sample statistic is a proportion, for example, the proportion in the sample responding "Yes" to a question. Calculate a 95% confidence interval for the population proportion (assume that the sample is a random sample). Describe the question asked, how the sample was collected, the sample size, and the population of interest. Write a short explanation of your findings for someone who knows no statistics. One possibility is the Gallup Poll Web site at www.gallup.com.
