Determine the t-value in each of the cases. Click the icon to view the table of areas under the t-distribution. (a) Find the t-value such that the area in the right tail is 0.005 with 16 degrees of freedom. 'Round to three decimal places as needed.) (b) Find the t-value such that the area in the right tail is 0.02 with 6 degrees of freedom. (Round to three decimal places as needed.) (e) Find the t-value such that the area left of the t-value is 0.15 with 28 degrees of freedom. [Hint: Use symmetry.] (Round to three decimal places as needed,) () Fine the critical t-value that corresponds to 30% confidence. Assume 16 degrees of freedom
