2 pts Question 21 A 95% confidence interval has a width proportional to the inverse of the square root of the sample size. sx.x + 2a/2) X- What happens to this interval as the sample size (n) approaches infinity? The interval becomes infinitely big because a bigger sample will collect outliers None of the other answers are correct. The sample mean becomes closer to the true mean of X, and the interval collapses to zero. Thus the true mean of X is known with (near) certainty. It is impossible for any sample size to go to infinity without out hitting a limit of a population size. DELL
