Suppose a batch of steel rods produced at a steel plant have a mean length of 150 millimeters, and a variance of 100. If 275 rods are sampled at random from the batch, what is the probability that the mean length of the sample rods would differ from the population mean by greater than 0.57 millimeters? Round your answer to four decimal places. Answer
