# 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?

Step 1

Given that,

If seatbelts have no effect on survival rate, there is less than a 0.0001 chance of getting these results.

Step 2

From the given data,

Hence, 0.0001 is a very low probability;

Thus it is ext...
