Excel Online Tutorial 2 laffic controllers resulted in proposals for modciation and redesign of the controllers' workstation. After consideration of several designs forthe workstation, three specific alternatives are selected as having the best potential for reducing controller stress. The key question is: To I.vhat extent do the three alternatives differ in terms of their effect on controller stress? A randomized block design is used to test the hypothesis of no difference in stress levels for the three workstation alternatives. The data for the experiment is located in the Microsoft Excel Online le below. Use at = 0.01 to test for any significant differences. Due to a recent change by Microsoft you will need to open the XLMiner Analysis ToolPak add-in manually from the home ribbon.
