A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 196.2 cm and a standard deviation of 1.9 cm. For shipment, 23 steel rods are bundled together. Find the probability that the average length of a randomly selected bundle of steel rods is between 195 cm and 196 cm. P(195 cm < ¯x < 196 cm) = Enter your answer as a number accurate to 4 decimal places. Answers should be obtained using z-scores correct to two decimal places.
