A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 183.7 cm and a standard deviation of 0.7 cm. For shipment, 28 steel rods are bundled together. Note: Even though our sample size is less than 30, we can use the z score because 1) The population is normally distributed and 2) We know the population standard deviation, sigma. Find the probability that the average length of a randomly selected bundle of steel rods is greater than 183.4 cm. Enter your answer as a number accurate to 4 decimal places.
