Critical value on ti-84

WebTranscript. If we want to be 95% confident, we need to build a confidence interval that extends about 2 standard errors above and below our estimate. More precisely, it's actually 1.96 standard errors. This is called a critical value (z*). We can calculate a critical value z* for any given confidence level using normal distribution calculations. WebMar 30, 2024 · A critical value is a cut-off value (or two cut-off values in the case of a two-tailed test) that constitutes the boundary of the rejection region (s). In other words, critical values divide the scale of your test statistic into the rejection region and the …
