The formula for estimation is: WebMar 25, 2024 · Therefore, the alpha value has to be split between both sides: 0.05/2 = 0.025 0.05/2 = 0.025. In other words, a 95% confidence interval comprises all values above the 2.5th percentile and below the 97.5th percentile (1-0.025 = 0.975). If you only have the percentile, Z scores are commonly derived from lookup tables.
