(a) Find the t-value such that the area in the right tail is 0.10 with 5 degrees of freedom. __ (Round to three decimal places as needed.)
(b) Find the t-value such that the area in the right tail is 0.025 with 29 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 0.15 with 14 degrees of freedom. [Hint: Use symmetry.] __ (Round to three decimal places as needed.)
(d) Find the critical t-value that corresponds to 99% confidence. Assume 26 degrees of freedom. __ (Round to three decimal places as needed.)
