could you please add step by step on how to do the work on excel?

1. Develop a simple linear regression equation for starting salaries using an independent variable that has the closest relationship with the salaries. Explain how you chose this variable. (5+5=10 points) 2. Present the simple lincar regression equation. identify and explain the coefficient of determination, intercept and regression coefficient, and significance of F-test. Based on this analysis, is your regression equation "good for use"? Explain. (2+2+2+2+2=10 points) 3. Provide a numeric example of how this regression cquation may be used to predict students' starting salaries. ( 5 points) 4. Develop a multiple regression equation for starting salaries using School Ranking, GPA, and Experience as independent variables, Is this regression equation "good for use"? Explain. (7+3=10 points) 5. If the multiple regression equation in the previous question is not "good for use", how would you suggest improving this multiple regression equation? Present the improved multiple regression equation. Give a numeric example of how this improved multiple regression equation may be used to predict students' starting salarics. (5+5+5=15 points)
