When calculating a confidence interval for the difference between two means, what information are you gaining?
The means are from both same population and different?
Thank you.

You are gaining information about the population. You are estimating the difference in population means by using the difference in the sample means. You also make a few assumptions, such as the populations have the same variance and the populations are normally distributed.
