You have been assigned the task of creating a multiple regression equation of at least three variables that explains Microsoft’s annual sales.Consider using a time series of data of at least 10 years. You can search for this data using the Internet.* Before running the regression, predict what sign each variable will be and explain why you make that prediction.* After running the regression, interpret the regression.* Does the regression fit the data well?* Does each predictor play a significant role in explaining the significance of the regression?* Are some predictors not useful?* If so, did you consider removing those and rerunning the regression?* Are the predictors related too significantly to one another?Submit your answers in a three- to four-page Microsoft Word document.
