A social scientist would like to analyze the relationship between educational attainment (in years of higher education) and annual salary (in $1,000s). He collects data on 20 individuals. A portion of the data is as follows: Salary Education 44 3 49 2 ⋮ ⋮ 34 0 Click here for the Excel Data File a. Find the sample regression equation for the model: Salary = β0 + β1Education + ε. (Round answers to 2 decimal places.) Salaryˆ= + Education b. Interpret the coefficient for Education. As Education increases by 1 unit, an individual’s annual salary is predicted to decrease by $6,430. As Education increases by 1 unit, an individual’s annual salary is predicted to increase by $8,590. As Education increases by 1 unit, an individual’s annual salary is predicted to increase by $6,430. As Education increases by 1 unit, an individual’s annual salary is predicted to decrease by $8,590. c. What is the predicted salary for an individual who completed 9 years of higher education?
