A safe generalization will broaden the survey to a population that closely resembles the group of people surveyed. Since the sample was taken from purchasers of a single auto manufacturer over the past five years, the safest generalization is a population with these same qualities. 
An automobile manufacturer wished to know which of two new paint colors were preferred on its newest line of vehicles. A~large simple random sample was taken from people throughout the USA who had purchased one of their vehicles in the~previous five years. What is the safest generalization of this survey? 

- Only those people who took this particular survey 
- All future customers of this automobile manufacturer 
- All people who have purchased from that manufacturer in the previous five years 
- Only those people who have purchased a vehicle in the previous five years 
- All vehicle owners in the USA
