A production manager at a wall clock company wants to test their new wall clocks. The designer claims they have a mean life of 16 years with a standard deviation of 3 years.

If the claim is true, in a sample of 37 wall clocks, what is the probability that the mean clock life would differ from the population mean by more than 0.7 years? Round your answer to four decimal places.
