part d is the one I'm unsure about. the question asks to find the critical t-value that corresponds to 80 % confidence assume 5 degrees freedom.

Determine the t-value in each of the bases 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 20 with 29 degrees of freedom 0.854 ( Round to three decimal places as needed i (b) Find the t value such that the area in the light taillis .01 with 29 degrees of freedom 2 462 (Round to three decimal places as needed !) (c) Find the I value such that the area left of the t value is 0 15 with 17 degrees of freedom [Hint. Use symmetry. ] 1 069 (Round to three decimal places as needed ) (d) Find the critical t value that corresponds to 80%% confidence Assume 5 degrees of freedom 2.060 (Round to three decimal places as needed)
