Overhead reach distances of adult females are normally distributed with a mean of 205.0 cm and a standard deviation of 7.8 cm. Find the probability that the mean overhead reach distance for a random sample of 20 adult females is greater than or equal to 203.7 cm. (Round your answer to three decimal places; add trailing zeros as needed.) The probability that the mean overhead reach distance for a random sample of 20 adult females is greater than or equal to 203.7 cm is
