While working with doctors on heart attack patients, we want to predict whether the patient will have a second heart attack within 1 year (yes = 1), based on two predictor variables: whether the patient completed an anger-control treatment course (yes=1), and the patient's score on a trait anxiety scale (a higher score means more anxious). Data on 20 patients is used to fit the following logistic regression:
Predictor Coef SE Coef Z P
Constant -6.36347 3.21390 -1.98 0.048
AngerTrt -1.02411 1.17108 -0.87 0.382
Anxiety 0.119045 0.0549790 2.17 0.030
What probability of second heart attack does the equation predict for someone who has taken the anger treatment course and whose anxiety level is 75?
