Supercavitation is a propulsion technology for undersea vehicles that can greatly increase their speed. It occurs above approximately 50 meters per second, when pressure drops sufficiently to allow the water to dissociate into water vapor, forming a gas bubble behind the vehicle. When the gas bubble completely encloses the vehicle, supercavitation is said to occur. Twelve tests were conducted on a scale model of an undersea vehicle in a towing basin with the average observed speed of 203.4 meters per second. Assume that the speed is normally distributed with known standard deviation of 9 meters per second. Test the hypothesis at Ho: u = 200 versus H1<200 at a = 0.01
