The automobile assembly line operation has a scheduled mean completion time, μ of 14.1 minutes. The standard deviation of completion times is 1.6 minutes. It is claimed that under the new management, the mean completion time has decreased. To test this claim, a random sample of 42 completion times under the new management was taken. The sample had a mean of 13.5 minutes. Assume that the population is normally distributed. Can we support, at the level of significance, the claim that the population mean completion time under new management is less than minutes?
