Feb 22, 2023 at 19:03 comment added rzmg @whuber thanks. I did do a search, and looked through those results. I just don't have the vocabulary/background to understand which question is the one I'm looking for. You are correct that I'm torn between describing data and testing hypotheses. Much of what I'm working on is simply describing a data set, but once in a while it would be useful to say [to use my example case], "here's the mean income of CEOs in this population, using the estimate for the population we just calculated" (i.e. not just describing the data). I know I'm probably explaining this poorly...

Feb 22, 2023 at 13:27 comment added whuber Welcome to CV, rzmg. This question is the opposite of too basic: it is so basic it has been asked and answered in a very great number of ways here on CV. A good use of our site, then, is to search it. Your situation very well might differ from any of those, but it is difficult to tell. Your sample doesn't sound random (that's one issue); and you seem torn between describing data and formally testing hypotheses. We would appreciate any clarifying edits you can make to your post.

Feb 22, 2023 at 12:23 comment added rzmg @HarveyMotulsky As in the original post, with some help I've calculated one CI/error for the first part of the project (estimating the size of the population). Now I've trying to figure out how to do that for a sample of the sample as it relates to that estimate. I wasn't expecting to see "go buy some stats books" -- is this just too basic a question for this forum?

Feb 22, 2023 at 5:13 comment added Harvey Motulsky You should be able to find information about computing the confidence interval of a mean in any statistics book. This would only be helpful if you assume your sample was randomly selected from the larger population.
Feb 22, 2023 at 3:33 comment added rzmg Trying to put another way, how would I find my error% at a confidence interval of 95 for the claim "the mean income of CEOs is X"?

Feb 22, 2023 at 2:58 comment added Harvey Motulsky The word "significant" is not helpful in your question, as it is ambiguous. Please try to ask your question in a quantitative way. It seems you are asking if the people selected because their income is high have a different average income that the other people. Of course the answer is yes. That is how the group was identified. I don't see any statistical question there.
