In statistics, a confidence interval (CI) is a tool for estimating a parameter, such as the mean of a population. [1] To make a CI, an analyst first selects a confidence level , such as 95%. The analyst then follows a procedure that outputs an interval.
The real part of every nontrivial zero of the Riemann zeta function is 1/2. The Riemann hypothesis is that all nontrivial zeros of the analytical continuation of the Riemann zeta function have a real part of 1 / 2 . A proof or disproof of this would have far-reaching implications in number theory, especially for the distribution of prime ...

[1] In statistical prediction, the coverage probability is the probability that a prediction interval will include an out-of-sample value of the random variable. The coverage probability can be defined as the proportion of instances where the interval surrounds an out-of-sample value as assessed by long-run frequency. [2]
Social Security could end up paying you $1.5 million, but it’ll depend on your filing age and the benefit you’re entitled to. Social Security cuts could result in smaller benefits down the line.

Financial guru Suze Orman once stated during an interview on the Afford Anything podcast: “If you only have a few hundred thousand dollars [in savings] or $1-2 million, I’m here to tell you ...
For the case of a single parameter and data that can be summarised in a single sufficient statistic, it can be shown that the credible interval and the confidence interval coincide if the unknown parameter is a location parameter (i.e. the forward probability function has the form (|) = ()), with a prior that is a uniform flat distribution; [6 ...
