Assume that the mean length of time required to complete the Columbus Marathon was 4.5 hours. Further assume that the standard deviation of the times required to complete the race was 0.50 hours. The winning time was 2.3 hours. Calculate the z-score for the runner with the winning time of 2.3 hours. Based on this z-score, is this time of 2.3 hours an outlier? Why or why not?
