Does blood pressure increase with age? A group of researchers want to know if systolic blood pressure increases with age. They designed an experiment where they took a random sample of 8 individuals and measured their systolic blood pressure and recorded their age. The data is presented in the table below: Systolic Blood Pressure (mmHg)
