Technically, this means that, if the experiment were repeated many times, 95% of the CIs computed at this level would contain the true population ...
A normal random variable will exceed + with probability , and will lie outside the interval with probability (). In particular, the quantile z 0.975 {\textstyle z_{0.975}} is 1.96 ; therefore a normal random variable will lie outside the interval μ ± 1.96 σ {\textstyle \mu \pm 1.96\sigma } in only 5% of cases.
