You are part of a multidisciplinary research group interested in the relationship between mental and physical health. Several data banks have been collected in your laboratory; you are assigned three on blood pressure. Your role is to ensure that the right analyses are done, and more importantly, that the interpretations are complete, appropriate.

Data Bank #1 - Blood Pressure Norms for 25-35 year olds

Before you can study the psychological correlates of blood pressure, you must first know some of its physiological determinants. Your medical colleagues have provided you with access to the mean systolic pressure measurements (mm HG) of a sample of 11 adults between the ages of 25 and 35.

Age	Pressure		Age	Pressure
29	127.95		27	127.24
31	128.04		25	124.26
34	127.58		33	130.84
30	128.81		26	129.68
35	129.96		28	124.82
32	128.33

Knowing that the equation of the line associated with this regression is = . + . :

1) Demonstrate the calculation of the variance associated with the prediction model 2) Demonstrate the calculation of the variance associated with the residual scores 3) What is the observed F in this analysis? 4) Report the critical F for an alpha of 5%, then draw a formal conclusion.
