Aviation and high-altitude physiology Is a specialty In the study of medicine. Let x = partial pressure of oxygen in the alveoli (air cells in the lungs) when breathing naturally available air. Let y = partial pressure when breathing pure oxygen 10,000 feet to 30,000 feet in 5000 foot Intervals for a random sample of volunteers. Although the medical data were collected using airplanes, they apply equally well to Mt. Everest climbers (summit 29,028 feet). 0.

O Reject the null hypothesis, there is Insufficient evidence that p > 0. O Fall to reject the null hypothesis, there Is insufficient evidence that p > o.
