How do i interpret a confidence interval
WebThe z value for a 95% confidence interval is 1.96 for the normal distribution (taken from standard statistical tables). Using the formula above, the 95% confidence interval is therefore: 159.1 ± 1.96 ( 25.4) 4 0. When we perform this calculation, we find that the confidence interval is 151.23–166.97 cm.
