Which of these is a direct consequence of reduced reaction time for drivers in traffic?

Which of the following best represents a typical minimum simple reaction time to a sound for a young, alert person?

A snowboarder practices reacting faster to a gate. Which training will most likely reduce their reaction time?

Which of these best describes the difference between reaction time and response time?

Which emergency safety recommendation is directly aimed at reducing drivers’ reaction times?

Which action would reduce a driver’s reaction time (make them respond faster) while driving?

Which behaviour will most likely increase reaction time in an emergency driving situation?

A student drops a ruler and another student catches it; the distance the ruler falls before being caught is used to estimate reaction time. Which physical quantity is directly calculated from that falling distance for the estimate?

A reaction-time experiment records reaction times with standard deviation 0.05 s. If you average many trials, what happens to the standard error of the mean?
