A 95% confidence interval for the population mean of (50, 60) implies that we are 95% confident that the true population mean lies between 50 and 60. In other words, if we were to take many samples and construct a confidence interval for each sample, approximately 95% of those intervals would contain the actual population mean. However, it does not guarantee that the population mean is within this range for this specific sample.
