A study of the effect of seatbelt use in head-on 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 that a 0.0001 chance of getting these results. The probability shows that the sample results (could or could not) have occurred by chance. It appears that there (is or is not) sufficient evidence to conclude that seatbelts do have an effect on survival rate.
