Use the given probability value to determine whether the sample results could easily occur bychance, then form a conclusion.

A study of the effect of seatbelt use inhead-on passenger car collisions found that drivers using a seatbelt had a64.1% survivalrate, while drivers not using a seatbelt had a41.5% survival rate. If seatbelts have no effect on survivalrate, there is less than a 0.0001 chance of getting these results. What do youconclude?
