8.3 Consider a logistic regression model with two predictors and the following parameters:

the intercept is α = 2, and the slopes are β1

= 0.5 and β2

= −0.3.

a. Compute the predicted odds when X1

= 2 and X2

= 5.

b. Compute the predicted odds when X1

= 3 and X2

= 5.

c. Based on your results to parts

(a) and (b), explain how the value of β1 can be interpreted.
