**Residual Analysis in Regression**

The data provided includes X-values, residuals, and a residual plot from a regression analysis. The question to consider is whether there is any evidence of a pattern in the residuals.

**Table of X-Values and Residuals:**

- X: 1, Residual: 1.67
- X: 2, Residual: 1.08
- X: 3, Residual: -0.12
- X: 4, Residual: -0.74
- X: 5, Residual: -1.47
- X: 6, Residual: -0.51
- X: 7, Residual: 0.12
- X: 8, Residual: 0.53
- X: 9, Residual: 1.05
- X: 10, Residual: 1.74

**Residual Plot Description:**

The residual plot features residuals on the Y-axis and X-values on the X-axis. The plotted points show a pattern:

- Positive residuals at X-values 1, 2, 9, and 10
- Negative residuals between X-values 3 to 5
- A curved or U-shaped distribution is visible from the scatter of points, suggesting a potential pattern.

**Question for Consideration:**

Is there evidence of a pattern in the residuals? Choose the correct answer below:

- A. No, the residuals appear to be randomly spread.
- B. Yes, the residuals show decreasing variation.
- C. Yes, the residuals show a distinct cyclical pattern.
- D. Yes, the residuals show a distinct curved pattern.

Based on the plot, the pattern looks like option D: the residuals show a distinct curved pattern.
