An experiment was conducted in order to determine if cerebral blood flow in human beings can be predicted from arterial oxygen tension (millimeters of mercury). Fifteen patients participated in the study, and the provided data were collected with the accompanying results. Test the hypothesis that 2 = 0 at the 0.05 level of significance against the alternative that B2 # 0. Click here to view the blood flow data and regression results.
