The tread life of tires mounted on light-duty trucks follows the normal probability distribution with a population mean of 60,000 miles and a population standard deviation of 3,000 miles. Suppose we select a sample of 5,000 tires and use a simulator to determine the tread life. What is the standard error of the mean?
