A race director is preparing for an upcoming marathon and estimates that the mean time to finish is 314 minutes. Assume that the times are normally distributed, with a standard deviation of 64 minutes. Use this table or the ALEKS calculator to find the percentage of times that are longer than 298 minutes. For your intermediate computations, use four or more decimal places. Give your final answer to two decimal places (for example 98.23%). 2 % X S ?
