A blood pressure measurement consists of two numbers: the systolic pressure
1.A blood pressure measurement consists of two numbers: the systolic pressure, which is the maximum pressure taken when the heart is contracting, and the diastolic pressure, which is the minimum pressure taken at the beginning of the heartbeat. Blood pressures were measured, in millimeters of mercury, for a sample of 6 adults. The following table presents the results.SystolicDiastolic1348710869115831056611377157103Part 1 of 2 Compute the least-squares regression line for predicting diastolic pressure (v) from systolic pressure (x).
