![### Regression Analysis Exercise
**Objective:** Use the given data to find the equation of the regression line. Examine the scatterplot and identify a characteristic of the data that is ignored by the regression line.
**Data Table:**
| \( x \) | 11 | 7 | 11 | 8 | 10 | 14 | 5 | 4 | 12 | 7 | 5 |
|---------|----|---|----|---|----|----|---|---|----|---|---|
| \( y \) | 7.34 | 6.91 | 13.34 | 7.14 | 7.62 | 9.22 | 5.94 | 5.46 | 7.9 | 6.24 | 5.85 |
**Task 1:** Create a scatterplot of the data. Choose the correct graph below.
- **Option A:** Scatterpoints evenly spread across x-axis (0 to 25) with no clear trend.
- **Option B:** Similar to A, slightly more vertical spread.
- **Option C:** Points increase diagonally from bottom left to top right, indicating a positive trend.
- **Option D:** Steep increase and concentrated pattern on the lower x-values.
**Task 2:** Find the equation of the regression line.
\[ \hat{y} = \_\_\_\_ + \_\_\_\_x \]
*(Round the y-intercept to two decimal places and the slope to three decimal places.)*
**Task 3:** Identify a characteristic of the data that is ignored by the regression line.
- **A:** There is no trend in the data.
- **B:** There is no characteristic of the data that is ignored by the regression line.
- **C:** There is an influential point that strongly affects the graph of the regression line.
- **D:** The data has a pattern that is not a straight line.
