Document Summary

Porphyrin is a pigment in blood protoplasm and other body uids that is signi cant in body energy and storage. The average adult has 38 milligrams of porphyrin per deciliter of blood, with = 12. Data for this problem are based on information taken from weatherwise (vol. 1), a publication of the american meteorological society. For a random sample of tropical cyclones, let x be the lowest pressure (in millibars) as a cyclone approaches, and let y be the maximum wind speed (in miles per hour) of the cyclone. Determine x, y and the correlation coe cient, r. (b) (3 pts. ) For the data above, what is the regression line equation predicting wind speed from pressure? (c) (2 pts. ) Calculate the residual when x = 975. (d) (3 pts. ) The data table below shows the results of the vcis (voluntary cooperative information system)
