WebSome points to consider: 95 % confidence is a confidence that in the long-run 95 % of the CIs will include the population mean. It is a confidence in the algorithm and not a statement about a single CI. In frequentist terms the CI either contains the population mean or it does not. It’s just one from the dance of CIs to cite Geoff Cumming.
