For this reason, he uses the following data collected on 100 individuals. The response variable is CHD which is 1 if coronary heart disease is present and 0 otherwise. The following linear probability model and logit model have been estimated: Linear probability: = - 0.53796 + 0.02181Age
Logit: = Using the linear probability model, find the age of a person for which the estimated chances of having coronary heart disease are 50%?

• A) 47.8 years old
