The accompanying data file shows Salary and Education for 20 individuals. a. Find the sample regression equation for the model: Salary =0+1 Education +. Note: Round your answers to 2 decimal places. b. Interpret the coefficient for Education. As Education increases by 1 year, an individual's annual salary is predicted to increase by $5,320. As Education increases by 1 year, an individual's annual salary is predicted to decrease by $5,320. 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 increase by $8,590. c. What is the predicted salary (in $1,000 s) for an individual who completed 8 years of higher education? Note: Do not round intermediate calculations. Round the final answer to 2 decimal places
