If the sample size is large, use the z-score. (The central limit theorem provides a useful basis for determining whether a sample is "large".) If the sample size is small, use Brandon Foltz 89,200 views 37:42 Using the TI-84 to Find a Confidence Interval for a Population Mean (ZInterval and TInterval) - Duration: 14:39. In this situation, neither the t statistic nor the z-score should be used to compute critical values. You can certainly run whatever confidence interval you are attempting, subtract your upper bound from your lower bound and divide by two.
