(Linear Regression1) Use the attached data for the following problem.residual_dataset.xlsx  The attached data contains variables X1, X2, and Y. X1 and X2 are independent variables, and Y is the dependent variable. Please conduct a multiple regression using these variables. Then, using the results of residuals, find an optimal regression model that best fits the attached data (i.e., the optimal model has a good result for residual test we studied). You must do everything using Excel. Then, save the entire process and submit it. The first tab of the Excel file to be submitted should contain the regression model that best fits the data you found.
