An engineer tested nine samples of each of three designs of a certain bearing for a new electrical winch. The following data are the number of hours it took for each bearing to fail when the winch motor was run continuously at maximum output, with a load on the winch equivalent to 1,9 times the intended capacity. A 16 16 53 21 17 25 3 21 45 19 34 Design B 18 27 34 34 32 17 43 C 21 17 23 32 21 18 21 28 19 Which design is the best and why? Use Excel to calculate different statistical measures.
