you will be finding an example of how proportion estimates are presented in the media. You will be looking for an online article from the past 5 years or so, that presents data in the form of a population proportion estimate. So, you're looking for something that has reliable survey results, and where the point estimate is provided to make a claim about a population in general.
Using the information from the article (n, point estimate for p), you will construct a 95% confidence interval. Be sure to include:
- an active and direct link to the original article
- a brief summary of the article
- reflect on any possible bias (survey bias, sample size, audience targeting, etc.)
- state what your variables are (n, p, critical value z, and E)
- what the 95% confidence interval is
