Sampling Distributions & 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.
