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 58.8 seconds. assuming that sigmaequals11.3 seconds, construct and interpret a 99% confidence interval estimate of the population mean of all students.
