A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 132.2-cm and a standard deviation of 1.4-cm. Find the probability that the length of a randomly selected steel rod is between 131.4-cm and 135.6-cm. P(131.4-cm < X < 135.6-cm) =  Enter your answer as a number accurate to 4 decimal places. Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted.
