A nurse is interested in whether there is a relationship between daily levels of stress and likelihood of a heart attack. The stress scores (predictor variable) and risk of heart attack values (criterion variable) from a small sample of participants are depicted below. (Values below are valid for this question only!)

Stress Score                                Risk of Heart Attack

(Higher values = more stress)     (Higher values = greater risk)

    

    1                                                     7

      9                                                     2

      8                                                     3

      5                                                     8

Set up the regression equation and use to predict the risk of heart attack for a person with a stress score of 8. The risk of heart attack predicted for a person with a stress score of 8 is?
