Nico has conducted an observational study to learn about how different personal experiences affect car purchases. Nico surveyed
300 new car buyers at the auto mall and found that 75% of the buyers were shopping for the same model of a car they have owned before. What conclusion can Nico make from his study? A.Owning the same model of a car previously causes a buyer to purchase that car again, but he cannot draw a cause-and-effect conclusion from an observational study.
B. There may be a link between owning a model of a car and buying that model again, but he cannot draw a cause-and-effect conclusion from an observational study.
C.There may be a link between owning a model of a car and buying that model again, and he can draw a cause-and-effect conclusion from an observational study.
D.Owning the same model of a car previously causes a buyer to purchase that car again, but he can draw a cause-and-effect conclusion from an observational study.
Nico surveyed 300 new car buyers at the auto mall and found that 75% of the buyers were shopping for the same model of a car they have owned before.
This is 225 customers out of 300.
When people are satisfied with their car's current company and brand and model, they can prefer the same thing again for the same better experience. But this is not 100% proven. We can only say that there may be a link between the two things.
Hence, the conclusion that can be drawn here is :
B. There may be a link between owning a model of a car and buying that model again, but he cannot draw a cause-and-effect conclusion from an observational study.
