WEBThe 95% Confidence Interval (we show how to calculate it later) is: The " ± " means "plus or minus", so 175cm ± 6.2cm means. 175cm − 6.2cm = 168.8cm to. 175cm + 6.2cm = 181.2cm. And our result says the true mean of ALL men (if we could measure all their heights) is likely to be between 168.8cm and 181.2cm.

WEBOct 11, 2023 · For a 95% confidence interval and a sample size > 30, we typically use a z-score of 1.96. The formula for a confidence interval is (mean – (z* (std_dev/sqrt(n)), mean + (z* (std_dev/sqrt(n)). So, the confidence interval is (85 – (1.96*(5/sqrt(30))), 85 + (1.96*(5/sqrt(30))) = (83.21, 86.79).
