... A confidence interval is just a point estimate “wrapped” with the standard estimated error of the point estimate. This is sometimes called “constructing a confidence interval.” The estimated error is t (why? because the population standard deviation is not given in the problem) multiplied by standar ...

... N in those histograms is the sample size you are drawing from the population. We will be exploring the distribution of the sample mean by drawing many samples from the parent distribution and examining the distribution of the sample means we get. Step 1. Describe the parent population. What distribu ...
