Softswift, a software developer, is trying to determine if any of three potential subcontractors has better programmers in order to outsource a development project. The three subcontractors agreed to test five programmers, using a standardized test provided by Softswift, as provided in the data in the Ch05Data.xlsx Excel workbook file for Prob05-14. Use the single factor ANOVA Excel tool to determine if there is a significant difference between the scores of programmers at the three contractors at the 5 percent level.
