Question

A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 237.1-cm and a standard deviation of 2.2-cm. Find the probability that the length of a randomly selected steel rod is greater than 240-cm. P(X > 240-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.
