Blood pressure: A blood pressure measurementconsists of two numbers: the systolic pressure, which is themaximum pressure taken when the heart is contracting, and thediastolic pressure, which is the minimum pressure taken at thebeginning of the heartbeat. Blood pressures were measured, inmillimeters, for a sample of 7 adults. The following table presentsthe results. The least-squares regression line=y=+b0b1x+24.83840.4499x, =se7.161065, =Σ−xx2407.43, and x=120.71are known for this data.
