Use the following information for questions:
An observational study has found that drivers who report that they routinely wear a seatbelt were less likely to have been given a traffic ticket for speeding in the past three years.
-A politician hears about this result and proposes a bill to finance a public education campaign to get people to wear seatbelts. He argues that if it works, it would reduce speeding as well. What would you conclude about his reasoning?
A) It is correct.
B) It is not correct because the relationship between seatbelt use and speeding tickets is probably due to confounding variables.
C) It is not correct because the cause and effect relationship is most likely in the other direction.
D) It is not correct because the results of an observational study cannot be extended to a population.

The politician's reasoning is flawed because the observed relationship between seatbelt use and receiving fewer speeding tickets could be influenced by confounding variables, such as a general attitude towards safety and law adherence, rather than seatbelt use directly causing a reduction in speeding.
