You perform 100 tests on one of two prototypes of the X15-24 line of products and a colleague performs another 100 tests on the other prototype.

Graphing of the tests is similar with your data as circles and your colleagues as crosses:

Your colleague notes that because the means of the measurements are virtually identical, there is no difference between the two prototypes and that therefore hers should be used because it will be cheaper to manufacture (which you concede). What counterarguments can you muster?
