Manufacturing Plant Machines
A mechanical engineer at a manufacturing plant keeps a close watch on the performance and condition of the machines. The following data are the weight losses (in milligrams) of certain machine parts due to friction when used with three different lubricants.
-Refer to Manufacturing Plant Machines graphics. State the null and alternative hypotheses to test whether there is a significant difference in mean weight losses among the three lubricants.
