(b) Would you consider it unusual to find a college student who never wears a seat belt when riding in a car driven by someone else? O A. Yes, because P(never)< 0.05. O B. No, because the probability of an unusual event is 0. O C. Yes, because 0.01 < P(never) < 0.10. D. No, because there were 135 people in the survey who said they never wear their seat belt.
