**Title: Calculating Degrees of Freedom for a Paired-Difference Test** **Description:** This section focuses on calculating the number of degrees of freedom (df) for a paired-difference test in statistics. **Instructions:** - **Objective:** Calculate the degrees of freedom (df) for a paired-difference test with specified observations and pairs. - **Given Information:** - \( n_1 = n_2 = 2 \) - \( n_1 \) and \( n_2 \) represent the number of observations in each sample. - \( n \) is the number of pairs. - **Calculation:** The degrees of freedom for a paired-difference test is calculated by subtracting one from the number of pairs. Therefore, the formula for degrees of freedom is \( df = n - 1 \). - **Input:** - Enter the calculated degrees of freedom in the provided box. An incorrect input is denoted by a red cross next to the input box. - **Example:** - If there are 13 pairs, then \( df = 13 - 1 = 12 \). In this scenario, the placeholder input shows "12" with an incorrect indicator (red cross), suggesting a mismatch with the expected input based on the number of pairs provided.
