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
55.755.7
sec.

Assuming that
sigmaσequals=
9.59.5
sec,
use a
.05
significance level to test the claim that the population mean is equal to
6060
sec.

What is the Z text statistic? What is the P Value? Based on the result, does there appear to be an overall perception of 1 min that is relatively close to an actual minute?
