Question

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)

    

   8                                                     6

     5                                                     0

     5                                                     1

     1                                                     9
