Delivery times for shipments from a central warehouse are exponentially distributed with a mean of 2.34 days (note that times are measured continuously, not just in number of days). A random sample of 144 shipments are selected and their shipping times are observed.Approximate the probability that the average shipping time is less than 2.05 days. Hint: Transform an exponential random variable to a standard normal random variable. Enter your answer as a number accurate to 4 decimal places.
