1. (A). We run the following:
> smoke = data.frame(Age=as.factor(rep(c("35-44","45-54","55-64","65-74","75-84"),rep(2,5))),
+ Type=as.factor(rep(c("Nonsmokers","Smokers"),5)),
+ Deaths=c(2,32,12,104,28,206,28,186,31,102), Exposure=c(18793,52407,10673,43248,5710,28612,2585,12663,1462,5317))
> smoke.fit = glm(Deaths ~ Age*Type , offset = log(Exposure),
+ family=poisson, data=heart)\
> smoke.fit = glm(Deaths ~ Age*Type , offset = log(Exposure),family=poisson, data=smoke)
> summary(smoke.fit)

Call:
glm(formula = Deaths ~ Age * Type, family = poisson, data = smoke,
offset = log(Exposure))
