Lower tail area of with degrees of freedom is
WebFor an upper-tail test, the p-value is the area under the curve of the t-distribution (with n−1 degrees of freedom) to the right of the observed t-statistic. For a lower-tail test, the p-value is the area under the curve of the t-distribution (with n−1 degrees of freedom) to the left of the observed t-statistic. WebThen the null hypothesis of the lower tail test is to be rejected if t ≤− t α, where t α is the 100(1 − α) percentile of the Student t distribution with n − 1 degrees of freedom. Problem. …

Did you know?
WebThat is, the lower the number of degrees of freedom the more area we find under the curve further away from 0. This is a major flattening for low values of the degrees of freedom but by the time we get to 5 degrees of freedom there is less than 2% of the area further away from 0 (in both tails) than the t-score 3.37.

WebAug 28, 2024 · As the degrees of freedom (total number of observations minus 1) increases, the t -distribution will get closer and closer to matching the standard normal distribution, a.k.a. the z -distribution, until they are almost identical. Above 30 degrees of freedom, the t -distribution roughly matches the z -distribution.
