Explain what the phrase "99% confident" means when we interpret a 99% CI for the true population mean u. The probability that the true population mean u falls in the calculated confidence interval is 0.97. O 99% of the observations in the population fall within the bounds of the calculated confidence interval. In repeated sampling. 99% of constructed intervals would contain the true population mean u. Ⓒ99% of the observations in the sample fall within the bounds of the calculated confidence interval.
