Question
**T-Value Determination in Various Cases for an Educational Resource**

This section provides instructions for determining the t-value in different scenarios using the t-distribution. It's imperative to refer to a table of areas under the t-distribution to find these values.

**Tasks:**

(a) **Objective:** Find the t-value such that the area in the right tail is 0.01 with 27 degrees of freedom.  
   **Instruction:** Round your answer to three decimal places.

(b) **Objective:** Find the t-value such that the area in the right tail is 0.05 with 6 degrees of freedom.  
   **Instruction:** Round your answer to three decimal places.

(c) **Objective:** Find the t-value such that the area left of the t-value is 0.25 with 7 degrees of freedom.  
   **Hint:** Use symmetry to assist in finding the value.  
   **Instruction:** Round your answer to three decimal places.

(d) **Objective:** Determine the critical t-value that corresponds to 95% confidence, assuming 30 degrees of freedom.  
   **Instruction:** Round your answer to three decimal places.
