The 200-meter race times at a state track meet are normally distributed with a mean of 13.56 seconds and a standard deviation of 2.24 seconds. Using the Standard
Normal Probabilities table, what is the approximate probability that a runner chosen
at random will have a 200-meter time less than 13.5 seconds? (5 points)
1) 0.4880
2) 0.6331
3) 0.7422
4) 0.5714
