13. Confidence intervals 1 Imagine you are estimating gravity on another world by timing how long it takes objects to fall from different heights. After fifty trials, you calculate an 80% confidence interval for the location of the true gravitational constant. Which of the following descriptions of the confidence interval is true? Pick ONE option The true gravitational constant has an 80% chance of being in your confidence interval. The average of the next fifty observations has an 80% chance of landing in your confidence interval. You have selected a method which, if repeated many times, produces intervals containing the true gravitational constant 80% of the time. Your confidence interval contains 80% of the distribution of fall-times. More than one of these answers are true. None of these answers are true.
