3. Determine the t-value in each of the caşes, (a) Find the t-value such that the area in the right tail is 0.20 with 24 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 24 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 0.05 with 14 degrees of freedom. [Hint: Use symmetry.](Round to three decimal places as needed.) (d) Find the critical t-value that corresponds to an area of 0.01 to the left. Assume 19 degrees of freedom. [Hint: Usesymmetry.](Round to three decimal places as needed.)
