I have a very basic question regarding confidence intervals. I am confused between two interpretations of confidence intervals.

Interpretation 1:

If repeated samples were taken and the 95% confidence interval computed for each sample, 95% of the intervals would contain the population mean.5% of the intervals would not contain the population mean

Interpretation 2: If we were to take 100 additional samples, 95 times out of 100, the population mean rate would fall between 2.5% and 17.5%.

Which of these would be correct?
