Use the 68-95-99.7 Rule for this question. In cognitive psychology experiments, researchers often measure reaction time—how long it takes a person to respond to a stimulus (like pressing a button when a light appears). In a simple reaction task, reaction times were normally distributed with a mean of 225 milliseconds (ms) and standard deviation of 25 ms. Approximately [a]% of people that complete this reaction task will have a reaction time between 175 and 275 ms. Approximately 68% of people that complete this reaction task will have a reaction time between [b1] and [b2] ms.
