This Question: 8 pts 9 of 20 (2 complete) Test: X Table of t-Distribution Areas Determine the 1-value in each of the cases. Click the icon to view the table of areas under the t-distribution. (a) Find the 1-value such that the area in the right tail is 0.005 with 27 degrees of freedom. (Round to three decimal places as needed.) (b) Find the 1-value such that the area in the right tail is 0.01 with 12 degrees of freedom. Area in (Round to three decimal places as needed.) right tail (c) Find the t-value such that the area left of the 1-value is 0.02 with 18 degrees of freedom. [Hint: Use symmetry (Round to three decimal places as needed.) Table VI (d) Find the critical t-value that corresponds to 60% confidence. Assume 19 degrees of freedom. t-Distribution (Round to three decimal places as needed.)
