Computer Homework 3 Develop a regression model using the manufacturing.xlsx file. Use Number of employees, Value Added by manufacturing, Value of industrial shipments, New capital expenditures, and End of year inventory to predict Cost of materials. Set up and solve this problem in Excel. Use highlighting to emphasize important cells. Insert text boxes to provide answers to the following questions, based on your final output (run the regression a second time, if appropriate): 1. What proportion of the variance in the dependent variable is accounted for by the combined effect of the independent variables? 2. Does it appear that an appropriate number of variables are used? Explain. 3. Were any variables in the initial solution not significant? If yes, list them. 4. Are there any outliers? 5. What is the final regression equation?
