Mathematically, we construct bounds using probability statements: $$P(L \leq \theta \leq U) = 1 - \alpha$$

Moving beyond single-point guesses, we encounter interval estimation. Rather than providing one value, we provide a range—a confidence interval—that is likely to contain the true parameter. It is a common misconception that a 95% confidence interval means there is a 95% probability the parameter is inside. In frequentist statistics, the parameter is fixed; it is the interval itself that is random. Therefore, the 95% refers to the process: if we repeated the experiment many times, 95% of the calculated intervals would contain the true parameter. mathematical statistics lecture
