Refer to the previous exercise. The data file also shows responses on whether a person smokes frequently. Software reports model −2 log-likelihood values of 1130.23 with only an intercept term, 1124.86 with also the main effect predictors, and 1119.87 with also all the two-factor interactions.

a. Write the model for each case and show that the numbers of parameters are 1, 5, and 11.

b. Find AIC values. Which of the three models is preferable?
