What mathematical concept do I need to read about to answer the following question?
Given:
- A population with an unknown mean, variance.
- A sample with a known size, mean, variance.
What is the range of values for 95% of the population data?
I initially thought that confidence intervals answered this question, but per https://math.stackexchange.com/a/1967239/25814 they provide a statement about the population mean, not its data.
