A race director is preparing for an upcoming marathon and estimates that the mean time to finish is 315 minutes. Assume that the times are normally distributed, with a standard deviation of 60 minutes. Use this table or the ALEKS calculator to find the percentage of times that are shorter than 453 minutes. For your intermediate computations, use four or more decimal places. Give your final answer to two decimal places (for example 98.23%). % X
