Reference no: EM1321040

Question: A researcher was looking at the relationship between heart disease (CHD) & a number of risk factors. The factors of interest were analyzed using a logistic regression equation of the form:

ln [p/(1-p)] = a + 2.3(X1) + (-3.1X2 ) + (-1.25X3 )+ 1.12(X2X3 )

α= -1.72

X1 = family history of CHD (0 = no, 1 = yes)

X2= sex (1=female, 0=male)

X3 = the average times per week a person exercises for at least 20 minutes

Calculate the change in the odds of CHD in males for each additional time they exercise on average each week.
