Three drivers competed in the same fifteen drag races. The mean and standard deviation for the race times of each of the drivers are given.Driver A had a mean race time of 4.01 seconds and a standard deviation of 0.05 seconds.Driver B had a mean race time of 3.96 seconds and a standard deviation of 0.12 seconds.Driver C had a mean race time of 3.99 seconds and a standard deviation of 0.19 seconds.Which driver do you predict will win the next drag race? Support your prediction using the mean and standard deviation.
