3. An experiment was performed to study the useful lifetime of batteries as a function of duty cycle, resistive load, and cutoff voltage. The data are given in QESHWO Data.xls. Open the Excel worksheet in MINITAB or copy the data from Excel and paste it into MINITAB. a. Use Stat> Quality Tools> Multi-Vari Chart to create a multi-vari chart of the data. Experiment with the order of the variables to find a multi-vari chart that's easy to understand. b. Send the results of your MINITAB analysis to a Word document including a copy of the data and your favorite multi-vari chart. c. Add a short statement to the Word document explaining the data and the results of your analysis.
