Linear Regression 1) x y a)Sketch a scatter plot of the data. b) Find the regression line for this data. a)Estimate y, when x = 20.

Linear Regression 2) AGE and SYSTOLIC BLOOD PRESSURE: The table below shows the age and systolic blood pressure for a group of people who recently donated blood. Age Blood Pressure a) Find the regression line for this data. b) Based on the regression equation, predict the blood pressure of a 15 year old; of a 60 year old: c) Predict the age of a person with a blood pressure of 130.
