Q

What happens to the confidence interval as sample size increases?

A

What happens to the confidence interval as sample size increases?

A. Doubles
B. Stays the same
C. Gets bigger
D. Gets narrower

If the sample size increases, the 95% confidence range stays the same;
however the 95% confidence interval gets narrow since the standard error decreases if the sample size is larger
