c. Determine the regression equation.
d. Use the regression equation to predict the salary for an executive who has been with the company for 14 years.
e. Draw regression line on graph
See the attached document for more data.
This solution provides guidelines on drawing a scatter graph, and determining the correlation coefficient and regression equation.
