Question

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. A. Identify the level of significance 1-alpha and the degrees of freedom, df = n B. Identify the level of significance alpha/2 and the degrees of freedom. d f = n - 1 C. Identify the level of significance alpha and the degrees of freedom, d f = n - 1 D. Identify the level of significance 1 - alpha/2 and the degrees of freedom, d f = n Find the critical value(s) using the 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.

Explanation / Answer

GIve the first step. Choose the answer below

Identify the level of significance and the degrees of freedom d.f. = n-1

Find the critical value(s) using the t-distribution table in the row with the correct degrees of freedom.

If the hypothesis test is left tailed use the second column (One tail) with negative sign.

If the hypothesis test is right tailed use the second column (One tail) with positive sign.

If the hypothesis test is two tailed use the third column (Two tails) with both negative and positive sign.
