, where μ is the mean and σ is the standard deviation. Using our information in this problem, we have

Using a z-table, we look up the z-score 1.43. The area under the curve to the left of, or less than, this value is 0.9236. This means the probability that the time is greater than this is 1-0.9236 = 0.0764.
