### Analysis of the Relationship Between Educational Attainment and Annual Salary

A social scientist aims to study the correlation between years of higher education and annual salary in thousands of dollars. Data has been collected from 20 individuals, with a sample displayed below:

| Salary | Education |
|--------|-----------|
| 34     | 3         |
| 66     | 1         |
| ...    | ...       |
| 33     | 0         |

#### Data File
- [Click here for the Excel Data File](#)

#### Task A: Construct the Regression Equation
Find the sample regression equation in the form: 
\[ \text{Salary} = \beta_0 + \beta_1 \times \text{Education} + \varepsilon \]
Round your answers to two decimal places.

#### Task B: Interpret the Coefficient for Education
Choose the correct interpretation:
- As Education increases by 1 year, an individual’s annual salary is predicted to increase by $4,690.
- As Education increases by 1 year, an individual’s annual salary is predicted to decrease by $8,590.
- As Education increases by 1 year, an individual’s annual salary is predicted to decrease by $4,690.
- As Education increases by 1 year, an individual’s annual salary is predicted to increase by $8,590.

#### Task C: Salary Prediction
Calculate the predicted salary for an individual with 7 years of higher education. Round the coefficient estimates to at least 4 decimal places and the answer to the nearest whole number.

\[ \text{Salary} = \$ \_\_\_\_ \]

This exercise illustrates the application of linear regression to understand the impact of educational attainment on salary, an essential analysis in social sciences and economics.

The table displayed contains two columns, "Salary" and "Education," with each row representing a distinct data entry. The "Salary" column provides numerical values representing salary figures, while the "Education" column contains numerical values that could represent levels of education completed.

Here is a transcription of the data:

| Salary | Education |
|--------|-----------|
|   34   |     3     |
|   66   |     1     |
|   89   |     4     |
|   56   |     3     |
|   71   |     7     |
|   80   |     2     |
|  111   |     7     |
|   51   |     0     |
|   23   |     7     |
|   36   |     2     |
|  100   |     1     |
|   35   |     1     |
|   71   |     6     |
|   68   |     9     |
|  163   |     5     |
|   56   |     0     |
|   86   |     5     |
|   58   |     4     |
|  128   |     9     |
|   33   |     0     |

This data could be utilized for analyzing the correlation between salary levels and education attainment, though the specifics of educational levels are not defined here.
