We have a population of all adult women. We take a random sample from this population and create a confidence interval. If we take many, many, many different samples from this population we will obtain many, many, many different sample means and confidence intervals created using the data from our samples. If we created many, many, many different confidence intervals in this manner 95% of them would capture the true mean weight of the population of all women.
