Chapter 4.1, Problem 38BSC

Using Probability to Form Conclusions. In Exercises 37-40, use the given probability value to determine whether the sample results could easily occur by chance, then form a conclusion.

38. Buckle Up A study of the effect of seatbelt use in head-on passenger car collisions found that drivers using a seatbelt had a 64.1% survival rate, while drivers not using a seatbelt had a 41.5% survival rate. If seatbelts have no effect on survival rate, there is less than a 0.0001 chance of getting these results (based on data from “Mortality Reduction with Air Bag and Seat Belt Use in Head-on Passenger Car Collisions,” by Crandall, Olson, Sklar, American Journal of Epidemiology, Vol. 153, No. 3). What do you conclude?
