The time it takes for a driver to react to the brake lights on a decelerating vehicle is critical in helping avoid rear-end collisions. Suppose that the reaction time for an in-traffic response to a brake signal from standard brake lights is normally distributed with a mean of 1.25 seconds and a standard deviation of 0.45 seconds. Suppose a random sample of 225 drivers is chosen and their reaction times are measured. What is the probability that the mean reaction time for the sample of 225 drivers is greater than 1.22 seconds
