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) 0 9 1 8 1 5 0 4 Set up the regression equation and use to predict the risk of heart attack for a person with a stress score of 3. The risk of heart attack predicted for a person with a stress score of 3 is?
