A car model is being designed to travel 640 km on a full tank of a particular unleaded gasoline. A prototype was tested by being filled with gasoline 30 times and at each time the distance traveled until the fuel indicator signaled empty was recorded. The average distance traveled until the fuel indicator signaled empty is 619.8 km, with a standard deviation of 36.6 km. Conduct a test of hypothesis to determine if there is sufficient evidence to say that this car can travel an average of 640 km with that particular unleaded gasoline. Use a 0.01 level of significance. A. Perform a complete test of hypothesis. B. Select here the conclusion for this test of hypothesis. O There is no sufficient evidence to say that the average distance travelled by this car model until the fuel indicator signals empty is not 640 km. O The average distance travelled by this car model until the fuel indicator signals empty is not 640 km.
