Inference conditions

As was hinted before, Table 6 of the report provides statistics, that is, calculations made from the sample of 51,927 people. What you would like though, is insight into the population parameters.

You answer the question, "What proportion of people in your sample reported being atheists?" with a statistic; while the question "What proportion of people on earth would report being atheists" is answered with an estimate of the parameter.

The inferential tools for estimating population proportion are analogous to those used for means in the previous lab: the confidence interval and the hypothesis test.

Take some time to write out the conditions for inference to construct a 95% confidence interval for the proportion of atheists in the United States in 2012.
