Ace asks. You answer out loud. Miss one and Ace explains it.

Pick a class and tap the chip. Ace reads each question in its own voice, listens to your answer, grades it like an epidemiology professor would, and saves every miss to a review deck.

Ace asksWhat does it mean for a method of constructing confidence intervals to have ninety-five percent coverage?
YouI'm not sure.
Here's the answer.If we repeatedly sampled and constructed intervals with this method, about ninety-five percent would contain the true population parameter. The parameter is fixed, but the intervals vary across samples. Remember: coverage describes the method over repeated samples, not a probability assigned to the fixed parameter after observing an interval.
