PART A - QUESTION 1 [19 points] An actuary for a life insurance company gathered data on 100 recently deceased male insured customers. For each customer, age at death of the insured customer was recorded, as well as ages at death of his father and mother. In addition, an indicator variable was set up to identify whether the customer was a smoker (1 = yes; 0 = no). Based upon the sample data available, the actuary wishes to predict a male customer’s age at death. Below is partial output of the multiple regression analysis.
