![**Statistical Analysis: Linear Regression**
This exercise involves finding the equation of a regression line using a set of data points.
**Task Overview:**
1. **Using the pairs of values for all 10 points:**
- Find the equation of the regression line.
2. **After removing the point with coordinates (1, 2):**
- Use the pairs of values for the remaining 9 points and find the equation of the regression line.
3. **Compare the results from parts (a) and (b):**
- Evaluate how the removal of the point (1, 2) affects the regression line.
**Step-by-Step Instructions:**
a. **What is the equation of the regression line for all 10 points?**
- Use the formula \(\hat{y} = \text{[write the intercept]} + \text{[write the slope]}x\). Ensure to round the values to three decimal places as needed.
**Note:** The problem prompts users to calculate the regression line equation interactively, so the specific numerical values for the intercept and slope are to be filled in based on calculation results.](https://content.bartleby.com/qna-images/question/d2d7eb0e-29ea-4a84-830a-dda0e7b4c374/627744bc-ed1c-48f7-8480-18a103ab9784/z03ifq_processed.jpeg)

Transcribed Image Text:The image displays a coordinate grid with the x-axis ranging from 0 to 10 and the y-axis ranging from 0 to 10. There are several blue dots placed on this grid as follows:
- A single dot located at the coordinates (1, 2).
- A 3x3 square arrangement of dots, spanning from (3, 5) to (5, 7).
These dots illustrate specific data points or positions on the grid, which could be used for various educational purposes such as teaching coordinate plotting or understanding geometric arrangements.
