Extracted text: Explain how to find the critical values for a t-distribution. Click the icon to view the t-distribution table. Give the first step. Choose the correct answer below. O A. Identify the level of significance 1-a and the degrees of freedom, d.f. = n. O B. Identify the level of significance a and the degrees of freedom, d.f. =n- 1. Oc. Identify the level of significance = and the degrees of freedom, d.f. =n- 1. O D. Identify the level of significance 1-a and the degrees of freedom, d.f. = n. 2 Find the critical value(s) using the given t-distribution table in the row with the correct degrees of freedom. If the hypothesis test is left-tailed, use the column with a sign. If the hypothesis test is right-tailed, use the column with a sign. If the hypothesis test is two-tailed, use the column with a sign.
