A research engineer for a tire manufacturer is investigating tire life for a new rubber compound and has built 16 tires and tested them to end-of-life in a road test. The sample mean and standard deviation are 60,139.7 and 3394.11 kilometers. Can you conclude, using that the standard deviation of tire life is less than 4000 kilometers
