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?

The probability shows that the sample results have easily occurred by chance. It appears that there sufficient evidence to conclude that seatbelts do have an effect on survival rate.
