Answer : ࠵?࠵? = ࠵? ! 2 ࠵?࠵? Explanation : Using error propagation, an expression for the uncertainty in computed time ࠵?࠵? was found. First, the partial derivative was calculated, simplified, and then the equation was switched to solve for ࠵?࠵? instead of ࠵? ! . It was assumed that g was precisely 9.8 m/s 2 and had no associated error, ࠵? ! .
Procedure An experiment was designed to measure reaction time. The hypothesis made for this experiment is that if reaction time is affected by distraction, then the reaction time will be longer. According to this hypothesis, it is generally believed that reaction time will indeed be significantly affected by distraction. Bullets for Experiment Design Consideration: The apparatus will be set up in a way that reaction time will be expressed by height reached on ruler once the participant catches the ruler. Measurement will be read by the first centimeter line mark on the ruler above the catcher’s fi
