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)
What is the numeric value of the y-intercept (a)?
Here, Y = stress scores and X = Risk of Heart Attack From the data, n = sample size =4... View the full answer
