Find the confidence interval
WebApr 13, 2024 · For example: fn ( p) = p2 is monotonic and increasing over the probabilistic range p ∈ [0, 1]. fn ( p) = ( p – 0.5) 2 is non-monotonic over the same range. A confidence interval for a monotonic function of p can be obtained by simply applying the same function, fn, to its lower and upper bounds.

WebDec 14, 2024 · The interval is calculated using the following steps: Gather the sample data. Calculate the sample mean x̅. Determine whether a population’s standard deviation is known or unknown. If a population’s standard deviation is known, we can use a z-score for the corresponding confidence level. 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. …
