Wire rope has many applications, especially in hoisting and suspension. The fatigue limit, measured in MPa, of wire rope was collected for 15 specimens each from three different manufacturers of similar wire rope diameters, as follows. (Image) a. Compare mean fatigue limits of the three manufacturers. Do the same for median fatigue limits. What do each suggest about the choice of manufacturer? If the two measures of central tendency suggest different choices, what does the difference suggest? b. Construct boxplots for each manufacturer using the built-in function in Excel. What extra information do you now have relative to part a? What conclusion do you draw about the difference in manufacturers with this extra information?
