Question

Determine the t-value in each of the cases. 1 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 0.25 with 17 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 8 degrees of freedom. Round to three decimal places as needed.) (c) Find the t-value such that the area left of the t-value is 0.005 with 8 degrees of freedom. [Hint: Use symmetry.] Round to three decimal places as needed.) (d) Find the critical t-value that corresponds to 90% confidence. Assume 9 degrees of freedom. Round to three decimal places as needed.)

Explanation / Answer
