Statistics - 8.4.1 Estimating Population Proportions

In our last video for calculating a confidence interval for one sample, we look at estimating population proportions. We calculate the critical value using the normal model, which we are getting quite good at, and then calculate the standard error, the margin of error and finally the confidence interval and interpret the resulting interval.
