Individuals do not respond to visual stimuli with different colors at the same speed. The time interval between presentation of a stimulus and initiation of a voluntary motor response is referred to as the reaction time. The evaluation of the reaction time gives an idea of the integrity and processing capabilities of the central nervous system. It is a simple tool to determine a person's motor-sensory relationship and related functions. It is used to evaluate a person's state of health and condition monitoring for better performance of mental activities that require high focus and speed in instant decision. An experimental study was conducted to compare people's reaction times to a red light versus a green light. When signaled with either the red or the green light, the subject was asked to hit a switch to turn off the light. When the switch was hit, a clock was turned off and the reaction time in seconds was recorded. The following dataset gives the reaction times for 10 individuals. Dataset is available at reaction time.csv Let X; denotes the reaction time in seconds of an individual to red light, and let Y; denotes the reaction time in seconds of an individual to green light. By finding a 95% confidence interval for the difference between the means μD = μx - μy, we can conclude that A: With 95% confidence, we have evidence to indicate that there is a difference between the reaction times of individuals to a red light versus a green light. B: With 95% confidence, we have NO evidence to indicate that there is a difference between the reaction times of individuals to a red light versus a green light.
