3) Find a recent survey (search on line/newspapers/ for: Pew, Harris, Gallop, NPR, CNN, Fox News polls, etc.). Bring in the actual article. In addition, attach YOUR

critique of the methodology and the way the results were presented (hints: did they use appropriate sampling methodology (identify: simple random, systematic,

stratified, cluster, etc.) were they accurate in their calculations? Should they have used confidence intervals instead of a point estimate or visa versa? Why? Did

they disclose their sampling frame (i.e. how they selected their participants?; how many people were surveyed? ). Did the data they collected answer the question? Were

their conclusions consistent with/supported by the data? Attach the article plus your responses to the above questions to the homework.
