WebThe confidence level equals 1 – the significance level. Consequently, the CVs for a significance level of 0.05 produce a confidence level of 1 – 0.05 = 0.95 or 95%. For example, to calculate the 95% confidence interval for our two-tailed z-test with a significance level of 0.05, use the CVs of -1.96 and 1.96 that we found above. WebHere Z is a numerical value calculated based on the alpha (alpha = 1- confidence level). For 95% of confidence level, alpha comes out to be 0.05 and Z= 1.96. Mathematically we use the Z table to calculate the Z value.
