HLT 362V Correlation Regression

HLT 362V Correlation Regression

SYSTOLIC AND DIASTOLIC BLOOD PRESSURE OF FEMALES

The following table represents systolic and diastolic blood pressure measurements of 40 females.

1. A) Use the Excel Analysis ToolPak to find the linear correlation coefficient for the systolic and diastolic measurements.
2. B) Use the Excel Analysis ToolPak to determine the linear regression equation that uses the systolic pressure to predict the diastolic pressure.
3. C) What is the best predicted value for diastolic pressure given that a woman has a systolic level of 100?
