Randomly selected statistics students participated in an experiment to test their ability to determine when 1 min (or 60 sec) has passed. Forty students yielded a sample mean of 56.0 sec. Assuming that ? = 9.5 sec, use a 0.05 significance to test the claim that the population mean is equal to 60 sec. Based on the result, does there appear to be an overall perception of 1 min that is relatively close to an actual minute?
