Randomly selected students participated in an experiment to test their ability to determine when one minute (or sixty seconds) has passed. Forty students yielded a sample mean of 59.4 seconds. Assuming that sigmaσ=10.3 seconds, construct and interpret a 95% confidence interval estimate of the population mean of all students. What is the 95% confidence interval for the population u? Based on the result, is it likely that the students' estimates have a mean that is reasonably close to sixty seconds?
