03. ScreenCast: Sampling Distributions and Confidence Intervals

In this video, you saw an example of how to build a confidence interval using the sampling distribution of the statistic that best estimates your parameter of interest. In this case, we used a sample mean height to estimate the population mean height.

You can interpret your confidence interval as We are 95% confident, the population mean falls between the bounds that you find. Notice that the percent and the parameter can both change depending on what you are building your confidence interval for, and what percentage you cutoff in each tail.
