SYSTOLIC AND DIASTOLIC BLOOD PRESSURE OF FEMALES
The following table represents systolic and diastolic blood pressure measurements
of 40 females.
A) Use the Excel Analysis ToolPak to find the linear correlation coefficient for the
systolic and diastolic measurements.
B) Use the Excel Analysis ToolPak to determine the linear regression equation that
uses the systolic pressure to predict the diastolic pressure.
C) What is the best predicted value for diastolic pressure given that a woman has
a systolic level of 100?
