Choose a recent poll on a subject you are interested
in. Be sure to include a link to the poll. If you need a resource,
you can begin with Gallup.com. Gallup polls are very reputable.
After you have located a poll, answer the following questions:
1. What was the topic of your poll and what
questions were asked?
2. What was the sample size of the survey?
What were the poll results?
3. What was the margin of error (MOE)?
Note that while all legitimate polls disclose this information, you may have to
read to the end of the article to find it. It is usually given as a +/-
figure.
4. Using the MOE, construct at least two
Confidence Intervals for results of the poll. Be sure to write the
intervals using appropriate interval format. Show calculations.
5. Interpret the confidence intervals. Use
complete sentences and include a common sense interpretation. That is,
how would you explain the results to someone who has never taken statistics.
