Consider the following estimated regression model relating annual salary to years of education and work experience.


Estimated Salary=10,916.11+2983.07(Education)+769.64(Experience)Estimated Salary=10,916.11+2983.07(Education)+769.64(Experience)

Suppose two employees at the company have been working there for five years. One has a bachelor's degree (88 years of education) and one has a master's degree (1010 years of education). How much more money would we expect the employee with a master's degree to make?

The regression model given is:

\[
\text{Estimated Salary} = 10,916.11 + 2,983.07(\text{Education}) + 769.64(\text{Experience})
\]

### Step-by-Step Process:
1. Both employees have the same number of years of experience, $5$ years. So we need to calculate their salaries based on their years of education:
   - **Employee 1**: Bachelor's degree with $8$ years of education.
   - **Employee 2**: Master's degree with $10$ years of education.

### Salary for Employee 1 (Bachelor's degree):
\[
\text{Estimated Salary}_{\text{Bachelor}} = 10,916.11 + 2,983.07(8) + 769.64(5)
\]
\[
\text{Estimated Salary}_{\text{Bachelor}} = 10,916.11 + 23,864.56 + 3,848.20 = 38,628.87
\]

### Salary for Employee 2 (Master's degree):
\[
\text{Estimated Salary}_{\text{Master}} = 10,916.11 + 2,983.07(10) + 769.64(5)
\]
\[
\text{Estimated Salary}_{\text{Master}} = 10,916.11 + 29,830.7 + 3,848.20 = 44,595.01
\]

### Difference in Salary:
\[
\text{Difference} = 44,595.01 - 38,628.87 = 5,966.14
\]

Thus, we would expect the employee with a master's degree to make **$5,966.14** more than the employee with a bachelor's degree.

Would you like more details or have any questions?

Here are some related questions to expand your understanding:
1. How would the salaries change if both employees had 10 years of experience instead?
2. What would be the expected salary of an employee with 12 years of education and 7 years of experience?
3. How sensitive is salary to changes in education compared to experience based on this model?
4. If the experience term were larger, how much more would experience impact salary compared to education?
5. How could we modify the regression model to include other factors like industry or job role?

**Tip**: In regression models, each coefficient represents how much the dependent variable (in this case, salary) is expected to change when the corresponding independent variable increases by 1, holding all other variables constant.
