Delivery times for shipments from a central warehouse are exponentially distributed with a mean of 1.67 days (note that times are measured continuously, not just in number of days). The standard deviation of an exponential distribution is equal to the mean of 1.67 days. A random sample of 97 shipments are selected and their shipping times are observed.

Use the Central Limit Theorem to find the probability that the meanshipping time for the 97 shipments is less than 1.37 days. Round your answerto 4 decimal places.
