WebTo test a hypothesis using the critical value of t, follow these four steps: Calculate the t value for your sample. Find the critical value of t in the t table. Determine if the (absolute) t value is greater than the critical value of t. Reject the null hypothesis if the sample’s t value is greater than the critical value of t. WebFeb 2, 2024 · Recall, that in the critical values approach to hypothesis testing, you need to set a significance level, α, before computing the critical values, which in turn give rise to critical regions (a.k.a. rejection regions). Formulas for critical values employ the quantile function of t-distribution, i.e., the inverse of the cdf:. Critical value for left-tailed t-test:
