I just need help answering the questions in the picture with the red x and the questions that aren't shown stating (g) Find a 99% confidence interval for B and interpret its meaning. (Use 2 decimals) lower limit ___upper limit ___Interpretation - for a one unit increase in oxygen pressure breathing only available air, the oxygen pressure breathing pure oxygen increases by an amount that falls outside the confidence interval- for a one unit increase in oxygen pressure breathing only available air, the oxygen pressure breathing pure oxygen increases by an amount that falls within the confidence interval -for a one unit increase in oxygen pressure breathing only air available, the oxygen pressure breathing pure oxygen decreases by an amount that falls within the confidence interval-for a one unit increase in oxygen pressure breathing only available air, the oxygen pressure and breathing pure oxygen decreases by an amount that falls outside the confidence interval

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, The (x, y) data pairs correspond to elevations from 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). y 44.8 33.7 4.2 (units: mm Hg/10) 26.2 16.2 13.9 (units: mm Hg/10) (a) Verify that Ex = 21.9, Zy = 134.8, Ex = 110.79, Ey = 4284.82, Exy = 687.12, and r 0.
