Braking A tire manufacturer is considering a newlydesigned tread pattern for its all-weather tires. Tests haveindicated that these tires will provide better gas mileage and longer tread life. The last remaining test is for brak-ing effectiveness. The company hopes the tire will allow a car traveling at 60 mph to come to a complete stopwithin an average of 125 feet after the brakes are applied.They will adopt the new tread pattern unless there isstrong evidence that the tires do not meet this objective.The distances (in feet) for 10 stops on a test track were129, 128, 130, 132, 135, 123, 102, 125, 128, and 130.Should the company adopt the new tread pattern? Testan appropriate hypothesis and state your conclusion.Explain how you dealt with the outlier and why youmade the recommendation you did.
