Hello; I need help answering these questions step by step in excel and interpreting the data using three and four variables. Thank you in advance :)

Find the best multiple linear regression (based on R2) using two independent variables. Observe Multiple R, R-squared, Significant F, P-values and interpret. Observe the residuals and standard residuals of the model. Use the following guidelines to assign performance rating on scale of 1-7. If the standard residuals is:

-3.00 and lower Rating of 1

-3.00 to -2.00 Rating of 2

-2.00 to -1.00 Rating of 3

-1.00 to +1.00 Rating of 4

+1.00 to +2.00 Rating of 5

+2.00 to +3.00 Rating of 6

+3.00 and higher Rating of 7

Find the best multiple linear regression using three independent variables. Observe Multiple R, R-squared, Significant F, P-values and interpret. Observe the residuals and standard residuals of the model. Assign ratings based on table above.

Find the best multiple linear regression using four independent variables. Observe Multiple R, R-squared, Significant F, P-values and interpret. Observe the residuals and standard residuals of the model. Assign ratings based on table above.
